Quick Start Procedure
Demo circuit 2032A can be set up to evaluate the performance of the LTC6430-15. Refer to Figures 2 and 3 for
proper equipment connections and follow this procedure:
Single-Tone Measurement:
Connect all test equipment as suggested in Figure 2.
1.The power labels of 5V and GND directly correspond to
the power supply. Typical current consumption of the
LTC6430-15 is about 160mA.
2.Apply an input signal to J1. A low distortion, low noise
signal source with an external high order low pass filter
will yield the best performance. The input CW signal is
–10dBm.
3.Observe the output via J2. The measured power at the
J2 connector should be about 4dBm.
Two-Tone Measurement:
Connect all test equipment as suggested in Figure 3.
1.The power labels of 5V and GND directly correspond to
the power supply. Typical current consumption of the
LTC6430-15 is about 160mA.
2.Apply to J1 two independent signals f1 and f2 from SG1
and SG2 at 400MHz and 401MHz respectively.
3.Monitor the output tone level on the spectrum analyzer.
Adjust signal generator levels such that output power
measures 1dBm/tone at the amplifier output J2, after
correcting for external cable losses, minimum loss
matching pads and attenuations.
4.Change the spectrum analyzer’s center frequency and
observe the two IM3 tones at 1MHz below and above
the input frequencies. The frequencies of IM3_LOW and
IM3_HIGH are 399MHz and 402MHz, respectively. The
measurement levels should be approximately –90dBc;
46dBm is a typical performance of OIP3 at 400MHz. For
this setup, the Rohde and Schwarz FSEM30 spectrum
analyzer was used. This SA has a typical 20dBm thirdorder intercept point (TOI). So, the SA input attenuation
is set to 20dB with an external 14dB attenuation pad
(matches DUT gain), resulting in an attenuation total
of 34dB. The system as described can measure OIP3
up to 50dBm.

OPERATION
Demo circuit 2032A is a highly linear fixed gain amplifier.
To configure the demo circuit 2032A for use in the 75Ω
CATV environment, a transformer with 1:1.33 impedance
ratio is added at the board’s input and output. These
transformers transform the differential 100Ω impedance
of the LTC6430-15 to single-ended 75Ω impedance. The
frequency range of the circuit is limited by the balun transformers. Hence, the demo board has a nominal working frequency range from 50MHz to 1000MHz. Figure 4 shows the
S-parameters of demo board.

Demo circuit 2032A is shipped with 75Ω F-type connectors (J1 and J2) at both input and output. Depending on
the user’s preference, the board may also accept other
connector types such as BNC or SMA. Please note that
the use of substandard connectors can limit the usable
bandwidth of the circuit.
The input and output transformers (T3 and T4) convert the
differential to single-ended 75Ω for compatibility with the
CATV environment, while preserving all the exceptional
characteristics of the LTC6430-15. In addition, the balun’s
excellent phase balance and the second order linearity of
the LTC6430-15 combine to further suppress second order
products across the entire CATV band. Figure 5 shows the
spurious products (in dBc) within the passband frequency
of the output third-order intermodulation (OIM3) and the
second harmonic distortion (HD2).

Additional Information
As with any RF device, minimizing ground inductance is
critical. Care should be taken with the board layout because
of the exposed pad packages. The maximum number of
minimum diameter vias holes should be placed underneath
the exposed pad. This will ensure good RF ground and low
The frequency appropriate choke (L1 and L2) and the
decoupling capacitors (C9, C10, C11 and C12) provide
bias to the RF ±OUT nodes. Only a single 5V supply is
necessary for the VCC pins on the device.

thermal impedance. Maximizing the copper ground plane
will also improve heat spreading and reduce inductance. It
is a good idea to cover the via holes with solder mask on
the back side of the PCB to prevent solder from wicking
away from the critical PCB to the exposed pad interface.
The DC2032A has a nominal working frequency range from
50MHz to 1000MHz. It is not intended for operation down
to DC. The lower frequency cutoff is limited by on-chip
matching elements.
Setup and Testing Signal Sources
The LTC6430-15 is an amplifier with high linearity performance; therefore, output intermodulation products are
very low. For this reason, it drives most test equipment
and test setups to their limits. Consequently, accurate
measurement of IP3 for a low distortion IC such as the
LTC6430-15 requires certain precautions to be observed
in the test setup and testing procedure.
Setup Signal Sources
Figure 3 shows a proposed IP3 test setup. This setup has
low phase noise, good reverse isolation, high dynamic
range, sufficient harmonic filtering and wideband impedance matching. The setup is outlined here:
a. High performance signal generators 1 and 2 (HP8644A)
should be used in the setup. These suggested generators have low harmonic distortion and very low phase
noise.
b.High linearity amplifiers to improve isolation. They
prevent the two signal generators from cross talking
with each other and provide higher output power.
c. A low pass filter to suppress harmonic contents from
interfering with the test signal.
d.The signal combiner from Mini-Circuits ADP-2-9 combines the two isolated input signals. This combiner
has a typical isolation of 27dB. For better VSWR and
isolation, use the H-9 signal combiner from MA/COM,
which features >40dB isolation and a wider frequency
range. Passive devices (e.g., combiners) with magnetic
elements can contribute nonlinearity to the signal chain
and should be used cautiously.
e. The attenuator pads, on all three ports of the signal
combiner, will support further isolation of the two input
signal sources. They will reduce reflection and promote
maximum power transfer with wideband impedance
matching.
f. The minimum loss matching pads, (Mini-Circuits BMP5075R or equivalents) are added to the test setup at the
DUT input and output. These matching pads transform
the DUT impedance from 75Ω to 50Ω to match the
characteristic impedance of modern RF instrumentation.
Testing Signal Sources
The testing signal should be evaluated and optimized before
it is used for measurements. The following outlines the
necessary steps to achieve optimization.
a. Apply two independent signals f1 and f2 from signal
generator 1 and signal generator 2 at 240MHz and
241MHz, while setting amplitude = –7dBm per tone at
the combined output.
b.Connect the combined signal to the spectrum analyzer
without the DUT (i.e. The combined signal, the minimum
loss matching pad, the F-type thru adaptor, the minimum loss matching pad and the spectrum analyzer;
at this point, the spectrum analyzer should read about
–18dBm/tone for each main tone power).
c. Adjust the spectrum analyzer for the maximum possible
resolution of the intermodulation products amplitude
in dBc relative to the main tone power. A narrower
resolution bandwidth will take a longer time to sweep.
Optimize the dynamic range of the spectrum analyzer by
adjusting input attenuation. First increase the spectrum
analyzer input attenuation (normally in steps of 5dB
or 10dB). If the IMD product levels decrease when the
input attenuation is increased, then the input power
level was too high for the spectrum analyzer to make a
dc2032af

DEMO MANUAL DC2032A
OPERATION
Testing the DUT
valid measurement. In other words, the spectrum analyzer 1st mixer was overloaded and producing its own
IMD products. If the IMD reading holds constant with
increased input attenuation, then a sufficient amount
of attenuation was present. Adding too much attenuation will raise the noise floor and bury the intended
IMD signal. Therefore, select just enough attenuation
to achieve a stable and valid measurement.
At this point, the input level has been established at
–7dBm per tone (–13dBm at the DUT), and the input IMD
from the test setup is well suppressed at –96dBc max.
Furthermore, the SA is setup to measure very low level
IMD components.
d. In order to achieve a valid measurement result, the
test system must have lower distortion than the DUT
intermodulation. For example, to measure a 46dBm
OIP3, the measured intermodulation products will be
–90dBc below the –19dBm per tone input level and
the test system must have intermodulation products
approx. –96dBc or better. For best results, the IMD or
noise floor should be at least –100dBc before connecting the DUT.
b. Fine tune the signal generator levels by a small amount
if necessary (<1dB), to keep output power at 1dBm per
tone at the amplifier output.
a. Insert the DUT, minimum loss matching pads and
output attenuator into the setup, inline between the
signal source and SA. The output attenuator should
match the DUT gain.
c. Measure output IMD level using the same optimized
setup as previous. Based on the output power level of
1dBm per tone, and knowing the IMD level, OIP3 can
be calculated.
