AMMP-6408
6 to 18 GHz 1 W Power Amplifier in SMT Package
Data Sheet
Description
Features
The AMMP-6408 MMIC is a broadband 1W power
amplifier in a surface mount package designed for use
in transmitters that operate in various frequency bands
between 6 GHz and 18 GHz. At 8 GHz, it provides 29 dBm
of output power (P-1dB) and 20 dB of small-signal gain
from a small easy-to-use device. This MMIC optimized
for linear operation with an output third order intercept
point (OIP3) of 38 dBm.

Notes:
1. Operation in excess of any one of these conditions may result in permanent damage to this device.
2. Combinations of supply voltage, drain current, input power, and output power shall not exceed PD.
3. When operating at this condition with a base plate temperature of 85°C, the median time to failure (MTTF) is significantly reduced.
4. These ratings apply to each individual FET.
5. Junction operating temperature will directly affect the device MTTF. For maximum life, it is recommended that junction temperatures be
maintained at the lowest possible levels.

Note:
6. Assume SnPb soldering to an evaluation RF board at 80°C base plate temperatures. Worst case for the channel temperature is under the
quiescent operation. At saturated output power, DC power consumption rises to 4.26 W with 1.14 W RF power delivered to load. Power
dissipation is 3.11 W and the temperature rise in the channel is 68.4°C. In this condition, the base plate temperature must be remained below
86.6°C to maintain maximum operating channel temperature below 155°C.

Notes:
1. Small/large-signal data measured in packaged form on a 2.4 mm connecter based evaluation board at TA = 25°C.
2. This final package part performance is verified by a functional test correlated to actual performance at one or more frequencies.
3. Specifications are derived from measurements in a 50 Ω test environment. Aspects of the amplifier performance may be improved over a
narrower bandwidth by application of additional conjugate, linearity, or power matching.
4. Preassembly into package performance verified 100% on-wafer published specifications at frequencies = 7, 12, and 17 GHz.

Note:

Biasing and Operation
The recommended quiescent DC bias condition for
optimum efficiency, performance, and reliability is
Vdd = 5 volts with Vg set for Idd = 650 mA. Minor improvements in performance are possible depending on
the application. The drain bias voltage range is 3 to 5 V.
A single DC gate supply connected to Vg will bias all gain
stages. Muting can be accomplished by setting Vgg to
the pinch-off voltage Vp.
A simplified schematic for the AMMP6408 MMIC die is
shown in Figure 17. The MMIC die contains ESD and over
voltage protection diodes for Vg, Vd1, and Vd2 terminals.
In a finalized package form, Vd1 and Vd2 terminals are
commonly connected to the Vdd terminal. The package
diagram for the recommended assembly is shown in
Figure 18. In finalized package form, ESD diodes protect
all possible ESD or over voltage damages between Vgg
and ground, Vgg and Vdd, Vdd and ground. Typical ESD
diode current versus diode voltage for 11-connected
diodes in series is shown in Figure 13. Under the recommended DC quiescent biasing condition at Vds = 5 V,
Ids = 650 mA, Vgg = -1 V, typical gate terminal current is
approximately 0.3mA. If an active biasing technique is
selected for the AMMP6408 MMIC PA DC biasing, the
active biasing circuit must have more than 10-times
higher internal current that the gate terminal current.
An optional output power detector network is also provided. A typical measured detector voltage versus out-
put power at 18 GHz is shown Figure 20. The differential
voltage between the Det-Ref and Det-Out pads can be
correlated with the RF power emerging from the RF output port. The detected voltage is given by,
V = (Vref – Vdet) – Vofs
where Vref is the voltage at the DET _R port, Vdet is a voltage at the DET _O port, and Vofs is the zero-input-power
offset voltage. There are three methods to calculate Vofs:
1. Vofs can be measured before each detectore measurement (by removing or switching off the power source
and measuring Vref – Vdet). This method gives an error
due to temperature drift of less than 0.01 dB/50°C.
2. Vofs can be measured at a single reference temperature. The drift error will be less than 0.25 dB.
3. Vofs can either be characterized over temperature and
stored in a lookup table, or it can be measured at two
temperatures and a linear fit used to calculate Vofs at
any temperature. This method gives an error close to
the method #1.
The RF ports are AC coupled at the RF input to the first
stage and the RF output of the final stage. No ground
wired are needed since ground connections are made
with plated through-holes to the backside of the device.

The AMMP Packaged Devices are compatible with high
volume surface mount PCB assembly processes.
The PCB material and mounting pattern, as defined in
the data sheet, optimizes RF performance and is strongly
recommended. An electronic drawing of the land
pattern is available upon request from Avago Sales &
Application Engineering.

Manual Assembly
• Follow ESD precautions while handling packages.
• Handling should be along the edges with tweezers.
• Recommended attachment is conductive solder
paste. Please see recommended solder reflow profile.
Neither Conductive epoxy or hand soldering is recommended.
• Apply solder paste using a stencil printer or dot
placement. The volume of solder paste will be dependent on PCB and component layout and should be
controlled to ensure consistent mechanical and electrical performance.
• Follow solder paste and vendor’s recommendations
when developing a solder reflow profile. A standard profile will have a steady ramp up from room
temperature to the pre-heat temp. to avoid damage
due to thermal shock.
• Packages have been qualified to withstand a peak
temperature of 260°C for 20 seconds. Verify that the
profile will not expose device beyond these limits.
A properly designed solder screen or stencil is required
to ensure optimum amount of solder paste is deposited
onto the PCB pads. The recommended stencil layout
is shown in Figure 21. The stencil has a solder paste
deposition opening approximately 70% to 90% of the
PCB pad. Reducing stencil opening can potentially
generate more voids underneath. On the other
hand, stencil openings larger than 100% will lead to
excessive solder paste smear or bridging across the I/O
pads. Considering the fact that solder paste thickness
will directly affect the quality of the solder joint, a
good choice is to use a laser cut stencil composed of
0.127 mm (5 mils) thick stainless steel which is capable
of producing the required fine stencil outline.
The most commonly used solder reflow method is
accomplished in a belt furnace using convection heat
transfer. The suggested reflow profile for automated
reflow processes is shown in Figure 22. This profile is
designed to ensure reliable finished joints. However, the
profile indicated in Figure 1 will vary among different
solder pastes from different manufacturers and is shown
here for reference only.

Note: No RF performance degradation is seen due to ESD up to 250 V HBM and 50 V MM. The DC characteristics in general show increased
leakage at lower ESD discharge voltages. The user is reminded that this device is ESD sensitive and needs to be handled with all necessary ESD
protocols.
