Ruggedness
power foldback to 10% if RF power devices exceed
safe operating conditions
power foldback and shutdown if RF power devices
exceed safe operating currents
power foldback to 10% when supply voltage is 24 V to
26 V and 30 V to 32 V; shutdown when supply
voltage is < 24 V and > 32 V
power foldback to 10% at VSWR extremes; continuous
analogue power foldback to maintain
100% duty cycle into mismatched loads
