*Note: Mounted on Al2O3 board (30 x 30 x 0.65mm) Fujitsu 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 4000. 3. The operating channel temperature (Tch) should not exceed 80C.
