Eudyna recommends the following conditions for the reliable operation of GaAs FETs:
1. The drain-source operating voltage (VDS) should not exceed 2 volts.
2. The forward and reverse gate currents should not exceed 0.2 and -0.05 mA respectively with
gate resistance of 4000Ω.
3. The operating channel temperature (Tch) should not exceed 80°C.
