GaAs PHEMT MMIC-Based Power up sequence

1. Connect common ports

a. Connect single GND lead

b. Connect all –Vg ports together

c. Connect all +Vd ports together

2. Connect the load, attenuator to protect the VNA.

3. Connect the input port, may have an attenuator at the input (perform the CAL

with the

loads before connecting the amplifier to the VNA).

4. Apply the –Vg voltage -1.0 Volts (Always apply –Vg first).

5. Apply the +Vd voltage +8 Volts (Then apply +Vd second).
