CAUTION: LOSS OF GATE VOLTAGES (Vg1, Vg2) WHILE CORRESPONDING DRAIN
VOLTAGES (Vdd) ARE PRESENT CAN DAMAGE THE AMPLIFIER.
The following sequence must be followed to properly test the amplifier. (It is necessary to add a fan to
provide air cooling across the heat sink of RMBA09501A.) Note: Vdd1, 2 are tied together.
Step 1: Turn off RF input power.
Step 2: Use GND terminal of the evaluation board
Step 3: Slowly apply drain supply voltages of
The PWB must be prepared with either an embedded copper slug in the board where the package is
to be mounted or a heat sink should be attached to the backside of the PWB where the package is to
be mounted on the front side. The slug or the heat sink should be made of a highly electrically and
thermally conductive material such as copper or aluminum. The slug should be at least the same
thickness as the PWB. In the case of the heat sink, a small pedestal should protrude through a hole in
the PWB where the package bottom is directly soldered. In either configuration, the top surface of the
slug or the pedestal should be made coplanar with the package lead mounting plane i.e., the top
surface of the PWB. Use Sn96 solder (96.5% Sn and 3.5% Ag) at 220ºC for 20 seconds or less to
attach the heat sink to the backside of the PWB. Then, using Sn63, the package bottom should be
firmly soldered to the slug or the pedestal while the pins are soldered to the respective pads on the
front side of the PWB without causing any stress on the pins. Remove flux completely if used for
soldering.
Specifications are based on most current or latest revision.

apply gate supply voltages as specified on
results sheet supplied with test board to
the board terminals Vgg1 and Vgg2.
+7.0 V to the board terminals Vdd1, 2.
Adjust Vgg to set the total quiescent
current (with no RF applied) Idq as per
supplied result sheet. [Gate supply
voltages (Vgg i.e., Vgg1, Vgg2) may be
adjusted, only if quiescent current (Idq1
and Idq2) values desired are different
from those noted on the data summary
supplied with product samples].
