FIELD: radio engineering, communication.
SUBSTANCE: microwave power amplifier comprises a main amplifier module comprising a controlled attenuator and a microwave power amplifier, an input envelope detector, an output envelope detector, a reflected power peak detector, a falling power peak detector, an antenna power sensor, a reflected power sensor, a subtractor, a linear adder, a nonlinear adder, two operational amplifiers, a reflector of a reflected power, an incident power generator, a harmonic filter.
EFFECT: linearizating the amplitude characteristic and protecting the output stage of the amplifier from exceeding the peak power, stabilizing the power of the output cascade.
