*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 80
°
C.
