Recommended Procedure for Biasing and Operation
CAUTION: LOSS OF GATE VOLTAGE (Vg) WHILE
DRAIN VOLTAGE (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:
the chip carrier. Slowly apply negative gate bias supply
voltage of -1.5V to Vg.
Connect the DC supply grounds to the ground of
Step 3:
+4V to Vd.
Slowly apply positive drain bias supply voltage of
Step 4:
current of Idq = 70mA.
Adjust gate bias voltage to set the quiescent
Step 5:
signal may now be applied at the appropriate frequency
band.
After the bias condition is established, the RF input
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 bias voltage (Vg).
