PRELIMINARY DATA SHEET • AP147-320
Application Board Bias Procedure
Step 1. Connect DC ground to the pad located in the top right-
hand corner of the board as indicated below.
Step 2. Connect Stage 1 collector bias voltage, V
at the bottom left side of the board as indicated below.
V
Step 3. Connect Stage 2 collector bias voltage, V
second pad in from the top left side of the board as indicated
below. V
Step 4. Connect Stage 3 collector bias voltage, V
pad at the top right side of the board as indicated below.
V
Step 5. Connect the bias control voltage, V
bottom right of the board as indicated below. V
to the same line as V
voltage supply.
NOTE: It is important that the V
source be adjusted such that 3.2 V is measured at the board.
The high drain currents will drop the drain voltage significantly if
long leads are used. Adjust the bias voltage to compensate.

Step 6. Connect the power control voltages, V
the middle two pads on the bottom of the board, as indicated
below. This is done to obtain a single control voltage supply.

Step 7. Apply RF at RF IN port at -20 dBm to start, then adjust
power level to 0 to 5 dBm.
Step 8. The V
output power level is achieved at RF OUT port.
Step 9. The pads in the upper left-hand corner, first from the left
and third from the left, are to be grounded.
