Fujitsu recommends the following conditions for the reliable operation of GaAs FETs:
1. The drain-source operating voltage (VDS) should not exceed 10 volts.
2. The forward and reverse gate currents should not exceed 2.2 and -0.1 mA respectively with
gate resistance of 2000Ω.
3. The operating channel temperature (Tch) should not exceed 145°C.
