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:
+5V to Vd.
Slowly apply positive drain bias supply voltage of
Step 4:
current of Idq = 600mA.
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).
An example auto bias sequencing circuit to apply negative
gate voltage and positive drain voltage for the above
procedure is shown below.
