Test Procedure for the Evaluation Board (RMPA2451-TB)
It is important that the following points be noted prior to
testing; Pin designations are as shown in Figure 2 and 4.
V
gg1
and V
gg2
are the negative Gate bias voltages
applied at the pins of the evaluation test board.
V
dd1
and V
dd2
are the positive Drain bias voltages
applied at the pins of the evaluation test board.
V
g1
and V
g2
are the negative Gate bias voltages applied
at the pins of the package.
V
d1
and V
d2
are the positive Drain bias voltages applied
at the pins of the package.
CAUTION: LOSS OF GATE VOLTAGES (VG1, VG2)
WHILE DRAIN VOLTAGES (VD1, VD2) ARE PRESENT
MAY DAMAGE THE AMPLIFIER.
The following sequence of procedures must be followed to
properly test the amplifier:
Step 1:
Turn the RF power OFF.
Step 2:
the ground of the DC supplies.
Use the GND terminals of the evaluation board for

Step 4:

Apply a nominal voltage of +5.0V to the V
to provide a second stage quiescent
, of 340 mA. Adjust V

Step 5:
(2.4 - 2.5 GHz) at an initial input power level of -10 dBm.
Apply an RF signal within the ISM frequency range
Step 6:
ments, a second RF signal generator with a frequency
difference of 1 MHz is required, along with an appropriate
power combiner. The test configuration should allow this
additional generator to provide the same input power level
as the first generator into the device. Intermodulation
readings may then be made at the required total output
power levels.
To perform intermodulation product measure-
Step 7:
increase the magnitudes of V
alternatively to operate at higher quiescent Drain currents,
the magnitudes of V
gg1
and V
accordingly.
To operate at lower quiescent Drain currents,
gg1
and V
gg2
as required,
gg2
should be decreased
Step 8:
sequence should be reversed.
