Test Procedure for the evaluation board (RMLA3565C-TB)

The following sequence of procedure must be followed to

properly test the power amplifier:

Step 1: Turn off RF input power.

Step 2: Use GND terminal of the evaluation board to

connect DC supply grounds and Pin 5.

Step 3: Apply drain supply voltage of +4.0V to evaluation

board terminal Vdd.

Step 4: After the bias condition is established, RF input

signal may now be applied.

Step 5: Follow turn-off sequence of:

(i) Turn off RF input power.

(ii) Turn down and off Vdd.
