5 GHz Low Noise Amplifier MMIC

Fairchild Semiconductor 

Test Procedure for Biasing and Operation

CAUTION: LOSS OF GATE VOLTAGES (VG1, VG2)

WHILE CORRESPONDING DRAIN VOLTAGE (Vd) IS

PRESENT CAN DAMAGE THE AMPLIFIER.

The following sequence of steps must be followed to

properly test the amplifier.

Step 3: Slowly apply positive drain bias supply voltage of

+4V to Vd.

Step 4: After the bias condition is established, RF input

signal may now be applied at the appropriate frequency

band.

Step 1: Turn off RF input power.

Step 2: Connect the DC supply grounds to the grounds of

the chip carrier.

Step 5: Follow turn-off sequence of:

(i) Turn off RF input power.

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