Microwave SLCs
Single Layer Capacitor Series
GENERAL INFORMATION
AVX offers a complete line of Single Layer Ceramic (SLC)
Capacitors with dielectric constants ranging from 14
(NP0) to 60,000 (X7R). Product offerings include standard SLC’s (with & without borders) in all dielectric families. Also available are Dual-Caps & Multi-Cap Arrays as
well as specialized components for DC Blocking applications.
Our Maxi & Maxi+ grain boundary barrier layer (GBBL)
Single Layer Ceramics provide a combination of high
capacitance, voltage rating and small footprints
unmatched in the industry and are ideally suited for
broadband bypass applications. Additionally, our “Z”
dielectric (also a GBBL material system) offers a cost
effective alternative to Z5U & Y5V dielectrics with a
much improved temperature coefficient over an expanded operating temperature range of –55°C to +125°C.
Standard terminations are Ti/W-Au and Ti/W-Ni-Au. All
terminations are sputtered providing excellent surfaces
for wire bonding and exceptional adhesion characteristics. Wire bond tests are performed on every material lot.
Bond strength must meet a minimum of 6 and 20 grams
for 1 and 2 mil Au wire respectively (as compared to MILSTD-883 limits of 3 and 8 grams) before being released
to production (40 bonds with each wire size, zero failures
permitted).
All parts are capable of meeting or exceeding the environmental & mechanical specifications in Table II.
In addition to an extensive offering of standard catalog
devices, custom designs (and prototypes) are available
upon request. Delivery of samples seldom exceeds two
weeks once design parameters have been established.

Maxi & Maxi+ Series:
Single Layer Ceramics With & Without Borders
GENERAL INFORMATION
Maxi and Maxi+ are both AVX proprietary intergranular
barrier layer dielectric formulations. Both use SrTiO3 as
their major constituent and have dielectric constants
exceeding 20,000 and 30,000 respectively. Grain boundary barrier layer (GBBL) capacitors have been well discussed in various literature sources and, while simple in
principle, their resulting electrical properties are dependent on a complex combination of materials and process
technology.
AVX’s Maxi & Maxi+ dielectrics have the distinctive
properties that are ideal for extremely broadband
by-pass capacitors. This built-in feature gives these products a unique disspersive effect that is illustrated in the
accompanying curves. AVX’s ability to control the
prerequisite relationships between materials and
process has resulted in dielectrics that make these
Single Layer Ceramics especially well suited for applications requiring high frequency performance well into the
millimeter band.
All Maxi & Maxi+ dielectrics exhibit X7R temperature
performance of ±15% from –55°C to +125°C. Electrical
characteristics, as outlined in MIL-C-49464, will meet
those specified for Class II dielectrics, rather than the
less stringent Class IV, which typically describes GBBL
dielectrics.

GD Series
Ultra-MAXI Series
The Ultra-Maxi Series is the latest addition to the AVX family of proprietary high k,
inter-granular barrier layer dielectic systems. This series is similar to our Maxi &
Maxi+ product offerings, but with the notable difference that the dielectric constant has been increased to 60,000 - double the previous high for our industry
leading GBBL formulations.
These new Single Layer Ceramic Capacitors, with X7R TCC and rated at 25VDC
(-55°C thru +125°C), set a new standard for circuit miniturization. On average, the
required board mounting area will be reduced by approximately two-thirds when
compared to an equivalent capacitance value for our Maxi+ series. The UltraMaxi series offers an ideal solution for broadband bypass applications where
high performance and the smallest footprint are the primary considerations.
The Ultra-Maxi Series is RoHS compliant - as are all AVX SLC products.
Terminations (Au over Ti/W) provide an excellent wire bonding surface and are
compatible with conductive epoxy and Au/Sn eutectic solder attach.
Samples and custom configurations are available on request.

Microwave Single Layer
X7S Capacitors
Z Dielectric With and Without Borders
GENERAL INFORMATION
This grain boundary barrier layer (GBBL) system was
developed as a replacement for conventional Z5U/Y5V
dielectrics. With X7S temperature characteristics, the Z
Series offers not only a significant improvement over the
TCC of these two dielectrics, but does so over a much
wider operating range of -55C to +125°C. Voltage ratings
of 50 and 100VDC are available.
The Z Series is offered in a range of five dielectric constants
(2,500, 5,000, 9,000, 14,000 and 18,000) and products are
available with & without borders.

Microwave SLC’s
GENERAL INFORMATION
In addition to the standard SLC products shown below,
AVX is now able to offer bordered versions in these
same dielectric families as detailed on the opposing
page utilizing micron resolution photolithography and
etching processes.
With borders precisely defined, these parts will be beneficial in those applications that require enhanced visual
definition during placement and wire bonding.
Additionally, bordered devices have proven effective in
reducing susceptibility to conductive epoxy electrode
bridging.
Custom designs to meet stringent circuit trace width
matching requirements are available upon request.

Multi-Cap Arrays
GENERAL INFORMATION
AVX Multi-Cap Arrays can be manufactured with 2, 3, 4,
5 or 6 capacitors on one single layer ceramic substrate.
These arrays are available in our X7S (Z), Maxi and
Maxi+ family of GBBL dielectrics and offer a broad
range of capacitance values as detailed in the accompanying tables.
These arrays have advantages over single components
in the form of smaller overall size, reduced handling and
lower average unit costs. They are, therefore, a good
choice for broad-band bypass applications where circuit
board layouts can utilize these configurations.
The designs, shown along with the range of maximum
capacitance values, represent typical parts. Since most
applications require specific form factors, custom
designs on all multi-cap arrays are available to meet
individual customer requirements and are offered with
quick turn around. No charge samples are generally
shipped within two weeks of the design sign-off.
Both standard and custom designs are available with
borders for those applications where conductive epoxy
run up exposes the parts to the possibility of shorting.
Maximum capacitance per pad for bordered devices
will be necessarily somewhat lower than shown on the
adjacent page.
2 and 3 cap arrays can be designed with different
capacitance values per pad in circuit designs where
identical values pad-to-pad are, for one reason or another, not altogether suitable.
Additionally, the dual-caps are available to match micro
strip widths as dictated by circuit considerations. When
mounted with the individual pads down, the need for
wire bonding is eliminated. The maximum capacitance
values indicated on the typical designs shown represent
capacitance per pad. Mounted with both pads down
puts two capacitors in series. The effective series capacitance (CEff), can be determined by 1/CEff = 1/C1 + 1/C2.
Contact the factory or your local AVX representative.

GX01 Series
Ultra-Broadband Capacitor
ADVANTAGES
APPLICATIONS
• Ultra-Broadband performance
• Ultra-Low Insertion Loss
• Semi-Conductor Data
Communications Customers
• X5R & X7S Characteristics
• Receiver Optical Sub-Assemblies
• Excellent Return Loss
• Transimpedance Amplifier
Customers
• Test Equipment Manufacturers
The GX Series was developed specifically to address DC
blocking issues from 160KHz (-3dB roll-off) to 40GHz. Most
applications will experience resonance-free insertion loss of
<0.4dB thru at least 40GHz. Insertion loss at higher frequencies
is in part dependent on installation parameters. Using AVX’s
patented precision thin film termination process, the part is
designed to be completely orientation insensitive with a standard
EIA 0201 footprint to minimize board space requirements. Both
Ni/Sn and Ni/Au terminations are available to cover a wide range
of attachment processes. All GX parts are RoHS compliant.
Au terminated units are wire bondable. Users may, therefore, find
these devices useful in bypass applications when wire bonding
is a necessary part of the manufacturing process.
More information can be obtained by contacting the factory or
your local AVX representative.

The GX0S Series was developed to address DC Blocking issues
from ~16KHz (-3dB roll-off) to 40GHz and was designed
specifically for mounting on strip lines with widths less than
20mils. In most applications, insertion loss (as shown below) will
typically fall in the range of 0.4dB. Insertion loss at frequencies
higher than 40GHz will be in part dependent on installation
parameters. These devices utilize AVX’s patented precision thin
film termination process and are especially well suited for high
volume solder assembly.
Both Ni/Sn and Ni/Au terminations are available to cover a wide
range of attachment processes.
Au terminated units are wire bondable. Users, therefore, may find
these devices useful in bypass applications when wire bonding is
a necessary part of the manufacturing process.
GX0S products (like all GX Series parts) are RoHS compliant.
More information can be obtained by contacting the factory or
your local AVX representative.

Introduction to
Microwave Capacitors
Microwave Capacitors in MICs
Typical Microwave Circuit Applications
Microwave MLC, SLC, or Thin-Film capacitor applications in
MIC circuits can be grouped into the following categories:
• DC Block (in series with an MIC transmission line)
• RF Bypass (in shunt with transmission lines)
• Source Bypass (in shunt with active device)
• Impedance Matching
This chapter discusses these applications and the performance parameters of microwave capacitors affecting these
applications.
DC Block
In the DC block application, the chip capacitor is placed in
series with the transmission line to prevent the DC voltage
from one circuit from affecting another circuit.
The capacitance is chosen so that the reactance is only a
fraction of an ohm at the lowest microwave frequency of
interest.
The largest value capacitor is used as long as the self-resonant
frequency is still much higher than the highest frequency of
interest.
RF Bypass
The RF bypass application is used to effectively short out the
RF to ground. The capacitor value is also picked to be as
large as possible without approaching the self-resonance of
the capacitor.
Source Bypass
The source bypass application is the same as the RF bypass
except the capacitor is used in conjunction with an active
device.
In this application the chip capacitor is butted up to the
source of the microwave FET device mounted on the MIC
circuit. This is done to minimize the length of the wire bond
from the source of the FET to the capacitor. The shorter the
wire bond, the lower the corresponding inductance.
The top side of the capacitor should be completely metallized so that the bond wire from the FET to the edge of the
capacitor is minimized.
The height of the capacitor must be less than or equal to the
height of the FET, usually about 0.005 inches. If the capacitor is higher than the FET, the capacitor will interfere with the
bonding tool when wire bonding to the FET.
Impedance Matching
The impedance matching application is to use the chip
capacitor to provide the required reactance at a specific
point in the circuit.
This is usually the most critical application in terms of the
capacitor maintaining a tight tolerance over temperature and
from unit-to-unit.
The other applications only require that the capacitance for
the DC block and RF bypass maintains a low reactance and
the tolerance can be as much as ±50%. Whereas the impedance matching function often requires ±1% tolerance.
In general, microwave capacitors should have the following
properties:
• Low-loss
• Operate very much below the self-resonant frequency
• The power handling capability should be commensurate
with the expected power performance of the circuit
• Capable of wire bonding and gap welding
• Low variation of capacitance over temperature
• Low unit-to-unit variations in capacitance
• Low dimensional variations from unit-to-unit

Microwave Parameters
Scattering Parameters
Generally, transmission and reflections coefficient measurements completely characterize any black box or network.
Transmission and reflections parameters — attenuation
(gain), phase shift, and complex impedance — can be
described in terms of a set of linear parameters called
“scattering” or “s” parameters. Knowing these characteristic
parameters, one can predict the response of cascaded
or parallel networks accurately. Unlike y or h parameters
which require short circuit and open circuit terminations, “s”
parameters are determined with the input and output ports
terminated in the characteristic impedance of the transmission line which is a much more practical condition to obtain
at RF and microwave frequencies.
To summarize, “s” parameters are more useful at microwave
frequencies because:
1. Equipment to measure total voltage and total currents
at the ports of the networks is not readily available.
2. Short and open circuits are difficult to achieve over a
broadband of frequencies because of lead inductance
and capacitance. Furthermore, these measurements
typically require tuning stubs separately adjusted at
each frequency to reflect short and open circuits to the
device terminals, and this makes the process inconvenient and tedious.
3. Active devices such as transistors and negative resistance diodes are very often not short- or open-circuit
stable.
There are four scattering parameters for a two-port network:
S11, S12, S21, and S22.
S11 is the reflection coefficient at the input port with the
output port terminated in a 50 ohm load.
S12 is the reverse transmission coefficient in a 50 ohm
system.
S21 is the forward transmission coefficient in a 50 ohm
system.
S22 is the reflection coefficient at the output port with the
input port terminated into a 50 ohm load.
The reflection coefficients can be directly related to the
impedance of the device by the equation:
Eq.1. ZIN/ZO = (1 + S11)/(1 - S11)
where ZIN= input impedance
ZO = characteristic impedance of
the transmission line
This equation also defines the Smith Chart.
Return Loss
Return loss is the ratio of the incident power to the reflected
power at a point on the transmission line and is expressed in
decibels. The reflected power from a discontinuity is
expressed as a certain number of decibels below the incident power upon the discontinuity. It can be shown that
32
return loss can be related to the reflection coefficient and
VSWR:
Eq. 2. RL (dB) = 10 * log (Pinc/Pref)
= 20 * log (Einc/Eref) = 20 * log (1/Rho)
Eq. 3.
Rho = (VSWR - 1)/(VSWR + 1)
Eq. 4.
VSWR = (1 + Rho)/(1 - Rho)
where Rho = reflection coefficient
RL = return loss
Pinc = power incident
Pref = power reflected
Einc = voltage incident
Eref = voltage reflected
VSWR = voltage standing wave ratio
By the above equation, when the reflection coefficient is 1,
the return loss is zero. In this case, no signal is lost and all
the signal incident upon the discontinuity was returned to the
source. As the reflection coefficient approaches zero, the
return loss approaches infinity. That is, the more perfect the
load, the less the reflection from that load.
The return loss can be improved by an attenuator.
Assume that we connect a perfectly matched 3 dB attenuator into a short circuit as shown in Figure 3.

The indicated 100 mw is decreased to 50 mw at the output
of the 3 dB attenuator. This 50 mw is reflected from the short
circuit back through the attenuator in the reverse direction
and one-half of this reflected power is lost in the 3 dB attenuator. The reflected power at the input is 25 mw. Notice the
return loss is equal to twice the attenuation because it is the
“round trip” loss. This example shows that VSWR is
decreased when attenuation exists on a transmission line
and also that a high VSWR can be decreased by placing an
attenuator in the line.
Mismatch Loss
Mismatch loss is a measure of power loss caused by reflection. It is the ratio of incident power to the difference between
incident and reflected power and is expressed in dBs as
follows:
Eq. 5. Mismatch loss (dB) = 10 * log
[Pinc/(Pinc - Pref)]
= 10 * log
[1/(1-Rho = 2)]

Insertion Loss Measurement
Insertion loss is measured by the substitution method. The
insertion loss of the measurement system is used as a reference. Then the DUT (Device Under Test) is inserted into the
setup and the new insertion loss is measured. The difference
between the two losses is the insertion loss of the DUT.
The insertion loss is measured using the test setup as shown
in Figure 5.
In order to accurately measure the insertion loss, source
VSWR and load VSWR must be extremely Iow. It is assumed
during calibration (loss of the measurement system with
the DUT removed from the test setup) that the VSWR of the
generator and the load does not contribute any mismatch
losses. As discussed in the section on mismatch loss, any
VSWR above 1.2:1 may cause a minimum error of 0.04 dB.
In addition, the two VSWRs may be additive or subtractive
depending on the phasing of the reflections. For example,
source and load VSWRs of 1.2:1 can add to create an error
of 0.08 dB. The mismatches usually exhibit themselves as
amplitude ripple as a function of frequency. It is important
when measuring low insertion losses that precautions are
taken to ensure low source and load VSWRs and to keep the
mismatch losses due to the two VSWRs to a small fraction
of the expected insertion loss of the DUT.
In using the scalar network analyzer it is a temptation to normalize the amplitude response regardless what the actual
response is during calibration. It is advisable to eliminate the
amplitude ripple first before normalizing the scalar analyzer.
One way is to make use of the fact that VSWRs can be
improved by the use of matched attenuators. Often, 10 dB
attenuators are placed before and after the DUT to provide a
minimum of 20 dB return loss which corresponds to source
and load VSWRs of less than 1.20:1. This will reduce the
uncertainties due to mismatch losses to less than 0.02 dB.
Return Loss Measurement
The return loss is measured by the following method: The
test port is terminated by a short circuit so that all the incident power is reflected. A detector on the bridge measures
this power and this power is used as the reference for the
incident power. The test port is then terminated by the DUT
and the reflected power now measured. The difference
between the power levels is the return loss.

• All incident power is reflected at the short circuit.

• An SWR bridge usually has a directivity of 35 to 40 dB.
In other words, only a minute fraction of the incident power
reaches the detector (the dotted line path) that is not
reflected off the short circuit.
• The DUT is substituted for the short circuit and the opposite port is terminated by a matched termination (50 ohms).
• The reflected power depends on the DUT and is sensed by
the detector.
• The return loss is the difference between this reflected
power and that measured with a reference short circuit.

Note that the insertion loss and return loss can be measured
simultaneously by using the dual trace feature of the Wiltron
Scalar Analyzer. Furthermore, the two measurements can be
done by using a controller such as the HP85 computer for
semi-automatic testing.
The calibration for 0 dB return loss can be improved by averaging the short circuit and open circuit reflected powers.
Since the phase difference is 180 degrees, the average
closely approximates the actual full reflection.
The decibel, abbreviated “dB,” is one-tenth of the international transmission unit known as the “bel.” The origin of the
bel is the logarithm to the base 10 of the power ratio. It is
the power to which the number 10 must be raised in order
to equal the given number. The number 10 is raised to the
second power, or squared, in order to get 100. Therefore,
the log of 100 is 2.
The decibel is expressed mathematically by the equation:
Eq. 6 dB = 10 * log (P2/P1)
P2 = larger power
P1 = lower power
The use of log tables can be avoided in practical applications
where exact values of the power are not required. One only
needs to know that a factor of 2 is equal to 3 dB and a factor of 10 is equal to 10 dB and the rest of the conversions
are derived from these two relationships. The use of dBs
reduces multiplication into an addition. For example:
3dB =
2
6dB = 2 x 2
=
4
9dB = 2 x 2 x 2 =
8
10dB =
10
20dB =
100
The technique is based on the fact that 3, 6, and/or 9 dB
can be added or subtracted (in some combination) to any
decibel value. Adding or subtracting 10 to a decibel value
simply multiplies or divides the number by ten. Examples:
1. 17dB = 20dB - 3dB
20dB is 10dB + 10dB or is equal to 100.
3dB is equal to 2
Therefore, 20 dB - 3dB = 100/2 = 50
2. 36dB = 30dB + 6dB
1000 x 4 = 4000
Decibel:
The decibel is not a unit of power but merely is a logarithmic
expression of a ratio of two numbers. The unit of power may
be expressed in terms of dBm, where “m” is the unit, meaning above or below one milliwatt. Since one mw is neither
above nor below 1 mw, 1 mw= 0 dBm.
Nepers:
An alternate unit called the neper is defined in terms of the
logarithm to the base “e.” e = 2.718.
1 neper = 8.686dB
1dB = 0.1151 neper

Rp, the parallel resistance is not shown as it is of concern
only at dc and low frequencies.
The primary capacitance, C, is typically determined by measurement at 1 MHz where the effects of Rs, Ls, and Cp
become negligible compared to the reactance of C. The
value of C determined at this low frequency is also valid
at microwave frequencies when the dielectric constant has
a very low variation versus frequency, as is typical in the
modern dielectrics employed in microwave capacitors.

Series and Parallel Resonance
Ideally, the impedance magnitude of a series mounted
capacitor will vary monotonically from infinite at dc to zero at
infinite frequency. However, the parasitics associated with
any capacitor result in a nonideal response.
Figure 9 shows the magnitude, :Z (F):, as a function of
frequency.
Figure 10 shows Z(f) on the Smith Chart, which includes
magnitude and phase.
Eq. 8. In general, an impedance is represented by Z=R + j X.
The Smith Chart maps the entire impedance half plane for
R > 0 into the interior of a unit circle. The Smith Chart is a
mapping of the reflection coefficient, S11, of an impedance.
S11 = (Z- ZO) / (Z + ZO). ZO is a reference impedance, typically 50 ohms, and is in the center of the chart. The central
horizontal axis is for X = O, with R < 50 to the left of center,
and R > 50 to the right of center.

Figure 10. SLC Impedance on Smith Chart
Because there is always some parasitic inductance associated with capacitors, there will be a frequency at which the
inductive reactance will equal that of the capacitor. This is
known as the series resonant frequency (SRF). At the SRF,
the capacitor will appear as a small resistor (RS). The transmission loss through a series mounted capacitor at its series
resonant frequency will be low.
At frequencies above the SRF, the capacitor begins to act
like an inductor.
When used as a DC block, the capacitor will begin to exhibit gradually higher insertion loss above the SRF. In other
words, the capacitor will cause a high frequency rolloff of its
transmission amplitude response.
When used as an RF bypass, as for the source of an FET, the
inductance will cause the FET to become unstable which can
cause oscillations or undesirable effects on the gain
response of the FET amplifier.
Beyond the SRF, there is a frequency called the parallel
resonant frequency (PRF). This occurs when the reactance of
the series inductor equals that of the parallel capacitor.
35
Introduction to
Microwave Capacitors
Electrical Model
At this parallel resonant frequency, the capacitor will appear
as a large resister whose value is RPRF defined as:
Eq. 9. RPRF = Rs x QP X QP; where,
QP = 1/RS
WP/CP
WP = 2␲fPRF
The parasitic parallel capacitance is usually very small which
results in a parallel resonant frequency that is much higher
than the series resonance.
For capacitor usage in RF impedance matching and tuning
applications, the maximum practical frequency for use is up
to 0.5 times the SRF.
For DC filtering and RF shorting applications, best performance is obtained near the SRF.
At frequencies above the SRF, but below the PRF, the SLC
can be used as a low loss inductor with a built-in DC block
for bypassing and decoupling.
The series resonant frequency (SRF) of an SLC can be
measured by mounting the capacitor in series on a 50 ohm
transmission line as shown in Figure 11.
CHIP CAPACITOR

Figure 11
At its series resonant frequency (SRF), the SLC will appear as
a small resistance. This measurement can be performed with
a vector network analyzer such as the Hewlett Packard
8510. The SRF is at the frequency for which the phase of the
input reflection coefficient, S11, is crossing the real axis on
the Smith Chart at 180 degrees.
The resonant frequency will be lowered by the inductance
associated with the bonding attachment to the capacitor
(i.e., bonding wires, ribbons, leads, etc.). The actual resonant
frequency of the capacitor by itself can be determined by
taking out the effects of the bonding attachment inductance.
Using the low frequency measurements of the primary
capacitance alone, the inductance of the capacitor can be
derived from the resonant frequency. With AVX SLC’s, the
inductance is low enough so that the practical operating frequencies achieved can be beyond 20 GHz.
36
Equivalent Series Resistance
The equivalent series resistance is the RS in the electrical
model. At the SRF, the ESR can be readily determined on the
Smith Chart display of the capacitor’s impedance. However,
the ESR is not necessarily constant with frequency and its
value is typically determined by an insertion loss measurement of the capacitor at the desired frequency.
The insertion loss is a combination of reflective and absorptive components. The absorptive component is the part
associated with the value of the ESR (i.e., the loss in RS).
Because of the low values of ESR in microwave capacitors
(on the order of 0.01 ohm), the insertion loss measurement
is very difficult to make, but can be made with a test fixture
similar to that shown in Figure 11, but with the input and output 50 ohm impedances transformed down to some more
convenient impedance level, Rref, to obtain a more accurate
measurement.
When used as a DC block in the transmission line test fixture,
the forward transmission coefficient, S21, and the input
reflection coefficient, S11, can be measured to determine:
Eq. 10. Dissipative Loss.
DL=(1-:S11:^2)/(:S21:^2)
Eq. 11. Reflection Loss.
RL=(1-:S11:^2) where S11 and S21 are expressed
as complex phasors.
From the dissipative loss, DL, the ESR can be determined
as:
Eq. 12. ESR = Rref * [1 - SQRT(DL)]/[1 + SQRT(DL)]
The ESR typically increases with operating temperature and
self-heating under high power. This increase can be seen
directly in the lab by measuring the insertion loss of the
capacitor as a function of temperature.
A low ESR is especially necessary in SLC’s when used in
series with transistors in low noise amplifiers, high gain
amplifiers, or high power amplifiers. For example, an ESR of
1 ohm in series with a base input impedance of 1 ohm would
result in a serious compromise in ampIifier gain and noise
figure by up to 3 dB.
Power Rating
The RF power rating of chip capacitors is dependent on:
• Thermal Breakdown
• Voltage Breakdown
Thermal Breakdown
Thermal breakdown is self-heating caused by RF power dissipated in the capacitor.
If the resultant heat generated is greater than what can be
conducted away through the leads or other means of heat
sinking, the capacitor temperature will rise.
Introduction to
Microwave Capacitors
Electrical Model
As the capacitor temperature increases, the dissipation factor and ESR of the capacitor also increase which creates a
thermal runaway situation.
The small signal insertion loss is used to determine the percentage of power which is dissipated in the capacitor.
For instance, if the insertion loss is:
0.01 dB then .2% of the incident power is lost as heat
0.10 dB then 2% of the incident power is lost as heat
1.00 dB then 20% of the incident power is lost as heat
The capacitor will heat up according to the amount of power
dissipated in the capacitor and the heat sinking provided.
Even very low ESR, 0.01 ohm at 1 GHz, can be significant
when passing power through a series mounted capacitor
into a typically low impedance bipolar transistor base input
with an input impedance of only 1 ohm. If 1% of 10 watts is
dissipated in the capacitor, this 100 milliwatt of power causes
a very large increase in the capacitor temperature dependent
on its heat sinking in the MIC circuit.
Voltage Breakdown
The voltage breakdown also limits the maximum power
handling capability of the capacitor.
The voltage breakdown properties of the capacitors is
dependent on the following:
• dielectric material
• voids in the material
• form factor
• separation of the electrodes
Most microwave capacitors have a DC voltage rating of 50
VDC. This is much greater than typical DC voltages of 3 to
15 volts present on an MIC circuit.
Dielectric Constant Measurement at
Microwave Frequencies
The measurement of dielectric constants at low frequencies
is easily done by measuring the capacitance of a substrate
of known dimensions and calculating the dielectric constant.
The resonance method is used in measuring dielectric
constants at microwave frequencies of metallized ceramic
substrates. This is based on the model of the high dielectric
constant substrate as a parallel plate dielectrically loaded
waveguide resonator. By observing the resonant frequencies
and knowing the dimensions of the substrate, the dielectric
constant is calculated by fitting the resonances into a table
of expected fundamental and higher order modes. This
method can be measured by connecting the corners of the
substrates to the center conductors of either an APC-7 or
Type N connector. The test setup is the same as for insertion
loss measurements. This method as described in the literature for an alumina substrate with a dielectric constant of
approximately 10 and a substrate height of 0.025 inches can
be measured to an accuracy of 2%. The Napoli-Hughes
Method uses an open circuit assumption for the unmetallized
edges which can be radiative. This inaccuracy is reduced if
thinner substrates or if higher dielectric constant substrates
are used which will tend to reduce radiation. Higher accuracy
can be achieved by metallizing all six sides of the substrate
except for the corners where the RF is coupled to the substrate. This method as reported by Howell provided more
consistent results.

Standing waves on the lossless transmission line:
An incident wave will not be reflected if the transmission line
is terminated in either matched load or if the transmission line
is infinitely long. Otherwise, reflected waves will be present.
In other words, any impedance will cause reflections.
Let us consider the case of a lossless transmission line terminated in a short line. In this case all of the incident wave
will be reflected. See Figure 15.
The dotted sine wave to the right of the short circuit in the
diagram indicates the position and distance the wave would
have traveled in the absence of the short circuit. With the
short circuit placed at X, the wave travels the same distance
back toward the generator. In order to satisfy the boundary
conditions, the voltage at the short circuit must be zero at all
times. This is accomplished by a reflected wave which is
equal in magnitude and reversed in polarity (shown by the
superimposed reflected wave and the resultant total voltage
on the line). Note that the total voltage is twice the amplitude
of the incident voltage at a quarter wavelength back toward
the generator and the total voltage is zero at one-half wavelength from the short.

The total voltage pattern is called a standing wave. Standing
waves exist as the result of two waves of the same frequency
traveling in opposite directions on a transmission line.
The total voltage at any instant has a sine wave distribution
along the line with zero voltage at the short and zero points at
half wave intervals from the short circuit. The points of zero
voltages are called voltage nodes and the points of maximum
voltage halfway between these nodes are called antinodes.
The voltage standing wave ratio is defined as the ratio of the
maximum voltage to the minimum voltage on a transmission
line. This ratio is most frequently referred to as VSWR (Viswar).

If the transmission line is terminated in a short or open circuit,

From the above equation the reflection coefficient is 1.0, and
the VSWR is infinite. If a matched termination is connected to
the line, the reflected wave is zero, the reflection coefficient is
zero, and the VSWR is zero.

Introduction to

Incorporation of Capacitors into Microwave Integrated Circuit Hybrids
A Microwave Integrated Circuit Hybrid (MIC) is a microwave
circuit that uses integrated circuit production techniques
involving such factors as thin or thick films, substrates,
dielectrics, conductors, resistors, and microstrip lines, to
build passive assemblies on a dielectric. Active elements
such as microwave diodes and transistors are usually added
after photo resist, masking, etching, and deposition processes have been completed. MICs usually are enclosed as
shielded microstrip to prevent electromagnetic interference
with other components or systems. This section will discuss
some of the important characteristics of MICs, such as:

MIC Substrates:
Microstrip employs circuitry that is large compared to the
wavelength of the frequency used with the circuit. For this
reason, the etched metal patterns often are distributed circuits with transmission lines etched directly onto the MIC
substrate. Figure 19 shows the pertinent dimensional parameters for a microstrip transmission line.
For the current discussion we are most interested in the higher microwave frequencies. The MIC circuit design requires a
uniform and predictable substrate characteristic. Several
types of substrates in common usage are: alumina, sapphire,
quartz, and beryllium oxide. Key requirements for a MIC substrate are that it have:
• Low dielectric loss
• Uniform dielectric constant
• Smooth finish
• Low expansion coefficient

The characteristic impedance of the microstrip line is dependent primarily on the following:
• Width of the conductor: Increase in the width “W” of the
conductor will decrease the ZO of the microstrip line.
• Height of the substrate: Increase in the height “H” of the
substrate will increase the ZO of the microstrip line.

The most popular substrate material is alumina which has a
dielectric constant of between 9.6 and 10.0 depending on
the vendor and the purity. Other substrates are used where
the specified unique properties of the material (beryllia for
high power, ferrites for magnetic properties) are demanded
by design.
Introduction to
Microwave Capacitors
Incorporation of Capacitors into Microwave Integrated Circuit Hybrids
MIC Metallization:
Capacitors:
MIC metallization is a thin film of two or more layers of metals. A base metallization layer is deposited onto the substrate, another layer may be optionally deposited on top of
this, and then a final gold layer is deposited onto the surface.
The base metallization is chosen for its adhesion to the substrate and for compatibility with the next layer.
The base metallization is usually lossy at microwave frequencies. The losses due to this metallization can be kept to
a minimum if its thickness does not exceed one “skin depth”
of the metal.
Skin effect defines a phenomenon at microwave frequencies
where the current travelling along a conductor does not penetrate the conductor but remains on the surface of the conductor. The “skin depth” indicates how far the microwave
current will penetrate into the metal. The “skin depth” is
smaller as the frequency increases.
By keeping the lossy metallization as thin as possible, more
of the microwave current will propagate in the top metallization gold layer and loss is minimized.
Typical metallization schemes used in the industry are:
• Chromium-Gold:
Cr-Au
• Nichrome-Gold:
NiCr-Au
• Chromium-Copper-Gold: Cr-Cu-Au
• Titanium-Tungsten-Gold:
TiW-Au
• Others
A lumped capacitor can be realized by the parallel gap
capacitance of an area of metallization on the top of the substrate to the ground plane. Values of capacitance that can be
obtained by this method are usually less than a few picofarads. At microwave frequencies if the capacitor size in any
one dimension begins to approach a quarter-wavelength, a
resonance will occur.
Large values of capacitance can be achieved with a dielectric constant between the capacitor plates while maintaining
the small size required for MIC circuits.
Chip capacitors can be fabricated on substrate with a dielectric constant up to 5000. This higher dielectric constant
allows a much smaller size capacitor for a given capacitance
value which is a very desirable feature both from the real
estate aspect and the self-resonance aspect.
MIC Components:
Microstrip has advantages over other microwave circuit
topologies in that active semiconductors and passive components can easily be incorporated to make active hybrid
circuits. It is possible to mix high and low frequency circuitry
to attain a “system-on-a substrate.”
Passive Components:
On MIC circuits, the passive components are either distributed or lumped elements. The distributed components are
usually realized by etched patterns on the substrate metallization. The lumped components are capacitors, resistors,
and inductors; and whenever possible components are
derived by etching them directly on the MlC metallization thin
film. Chip components are used when they offer advantages
such as:
• Component values are beyond that realizable by thin film
techniques on the MIC substrates,
• Smaller size is required,
• High power capability is required.
Capacitors, resistors, and inductors are discussed in the
following:
Resistors:
MIC resistors are often realized by using a resistive base layer
on the MIC substrate metallization, and by etching the proper pattern to expose the resistive layer in the MIC circuitry.
The exact value of the resistor is determined by:
• resistivity of the resistive base layer, and
• length and width of the resistor.
Thin film resistive base layers are usually the following:
• tantalum nitrite, or
• nickel-chrome (nichrome).
When chip resistors are used, they are mounted and connected in the same way as the chip capacitors.
Inductors:
Inductors are often realized by using narrow etched
microstrip lines which provides inductance on the order of
1 to 5 nanohenrys.
Higher values up to 50 nanohenrys are obtained by etching
a round or square spiral onto the MIC metallization.
Even higher values can be obtained by using wound wire
inductors or chip inductors which are wire coils encased in a
ceramic.
Both types of discrete inductors are attached to the circuit
by the same means as the capacitors.

Active components:
The active devices in the MIC circuit can be made of entirely
different materials than the substrates and are usually
attached to the substrates by eutectic soldering or conductive epoxy.
Typical active devices on MIC circuits are the following:
• GaAs FETs
• Bipolar Transistors
• Schottky Barrier Diodes
• PIN Diodes
• Various other Semiconductors
The active devices can be either in:
• a plastic or ceramic package with metal leads, or
• chip form.
The packaged devices are commonly used at a lower
frequency range than the chip devices since they exhibit
more parasitic circuit elements that limit their performance at
higher frequency.
The advantages of packaged devices are protection of the
devices during transport and mounting, ease of characterization, and ease of mounting onto the MIC circuit.
Chip Component Attach:
The methods of attachment of the chip components to the
substrate are usually by:
• eutectic solder die attach, and
• epoxy die attach.
1. Eutectic Die Attach
The eutectic die attach method can be used with several
alloys. Eutectic defines the exact alloy combination at which
the solidus to liquidus transition takes place at one particular
42
temperature. Other combinations have transition states with
wider temperature ranges. For instance, the eutectic temperature for the following alloys are:
Table III
Alloy
Gold Germanium
Gold Tin
Eutectic
Composition
Eutectic
Temperature
88% Au 12% Ge
80% Au 20% Sn
356°C
280°C
For best results, the eutectic attach is performed under an
inert gas atmosphere, typically nitrogen, to reduce oxidation
at high temperatures. The eutectic must be selected so that
the die attach operations will not interfere with prior soldering operations and itself will not be disturbed by subsequent
process steps. The metallization should be able to undergo
400°C without any blistering or other adhesion degradation.
2. Epoxy Die Attach
The epoxy die attach method uses silver or gold conductive
particles in an epoxy. The epoxy for chip attach on MIC
circuits is a one-part type which cures at temperatures of from
125°C to 200°C. The curing time is a function of temperature.
A cure time of 30 minutes at 150°C is a good compromise for
high reliability and a reasonable cure time.
Chip Components Interconnection:
The chip components are interconnected to the MIC circuit
by means of:
• wire bonding, and
• miniature parallel gap welding.
