PRELIMINARY INFORMATION

Test

Procedure

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

AMPLIFIER. THIS AMPLIFIER IS AN ESD SENSITIVE DEVICE.

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

Step 1 Slowly apply Gate Voltage (typical Vpinch-off= -

1.5V) to terminal VG.

Step 2 Slowly apply Drain Voltage at VD (<+5 volts)

and monitor drain current Ids. Adjust negative

voltage VG to set the drain current (Ids) to

approximately 1.2 A. Adjust the drain voltage

VD to nominal +8 volts (adjust Gate Voltage VG,

if needed, to maintain the drain current at Ids.

Step 3 After the bias condition is established, RF input

signal may now be applied at the appropriate

frequency band.

Step 4 Follow Turn-off sequence:

(i) RF input power=off,

(ii) VD=off,

(iii) VG=off.
