MGP488 50 handbook, halfpage VSWR = 5 PLnom (W) VSWR = 1 The transistor has been developed for use with unstabilized supply voltages. As the output power and drive power increase with the supply voltage, the nominal output power must be derated in accordance with the graph for safe operation at supply voltages other than the nominal.
