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. The graph shows the permissible output power
under nominal conditions (VSWR = 1), as a function of the
expected supply over-voltage ratio, with VSWR as
parameter.
The graph applies to the situation in which the drive
(P

/P

) increases linearly with supply over-voltage
ratio.
