Procedure

for Biasing and

Operation

CAUTION: LOSS OF GATE VOLTAGES (Vg) WHILE DRAIN VOLTAGES (Vd) IS PRESENT MAY DAMAGE THE

AMPLIFIER CHIP.

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

Step 1: Turn off RF input power.

Step 2: Connect the DC supply grounds to the grounds

of the chip carrier. Slowly apply negative gate

bias supply voltage of -1.5 V to Vgs.

Step 3: Slowly apply positive drain bias supply

voltages of +4 V to Vd.

Step 4: Adjust gate bias voltage to set the quiescent

current of Idq=105 mA.

Step 5: After the bias condition is established, RF input

signal may now be applied at the

appropriate frequency band.

Step 6: Follow turn-off sequence of:

(i) Turn off RF Input Power

(ii) Turn down and off drain voltage (Vd).

(iii) Turn down and off gate voltage (Vg).
