RMWB24001
24 GHz Buffer Amplifier MMIC
PRODUCT INFORMATION
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: Connect the DC supply grounds to the grounds
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 +4 V to Vd.
Step 4: Adjust gate bias voltage to set the quiescent
current of Idq=70 mA.
Step 5: After the bias condition is established, 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).
