PRODUCT INFORMATION

Test Procedure

for the Evaluation Board

The following sequence must be followed to properly test the amplifier:

Step 1: Turn off RF input power.

Step 2: Connect the DC supply grounds to the GND of

the evaluation board.

Step 3: Set Vab= -6V, Vee= -6V.

(Adjusting Vab provides quiescent current

control to optimize performance, not to

exceed -4V)

Step 4: Slowly apply supply voltage of +3.3 V to the

board terminal Vdd.

Step 5: Using Switch Logic Control Table below

Set up logic for desired output.

Switch Control “0” Voltage = 0 V

Switch Control “1” Voltage= +3.3 V

Step 6: After the bias condition is established, RF input

signal may now be applied at the appropriate

frequency band and power level.

Step 7: Follow turn-off sequence of:

(i) Turn down and off Vdd.

(ii) Turn off RF Input Power.

(iii) Set Vab and Vee to 0 V.
