Procedure

for biasing and

operation)

CAUTION: LOSS OF GATE VOLTAGE (VG) WHILE DRAIN VOLTAGE (VD) IS PRESENT CAN DAMAGE THE

AMPLIFIER.

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 ground

of the chip carrier.

Slowly apply negative gate bias supply voltage

of -1.5 V to Vg.

Step 3: Slowly apply positive drain bias supply voltage

of +5 V to Vd.

Step 4: Adjust gate bias voltage to set the quiescent

current of Idq=1000 mA.

Step 5: After the bias condition is established, the 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 bias voltage (Vg).

Note:

An example auto bias sequencing circuit to apply negative gate voltage and positive drain voltage for the above procedure is

shown below.
