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 24V to 
26V and 30V to 32V;  shutdown when supply voltage 
is <24V and >32V

power foldback to 10% at VSWR extremes;  continuous 
analogue power foldback to maintain 100% duty cycle 
into mismatched loads

The specifications in this section pertain only to the combination of a 5W, 50W or 100W power amplifier 
with a TB8100 reciter.
