*Note:
Mounted on Al2O3 board (30 x 30 x 0.65mm) Eudyna recommends the following conditions for the reliable operation of GaAs FETs: 1. The drain-source operating voltage (VDS) should not exceed 3 volts. 2. The forward and reverse gate currents should not exceed 0.2 and -0.075 mA respectively with gate resistance of 4000Ω. 3. The operating channel temperature (Tch) should not exceed 80°C.
