Abstract
An amplitude stabilized power amplifier having a power splitter for dividing the power of an input signal into a predetermined number of channels, a plurality of amplifier modules for amplifying the power of each of the channels divided by the power splitter, and a power combiner for combining the amplified power signals to provide an amplified output signal. One of the channels of the power splitter is provided with a voltage controlled phase shifter whose phase shift is controlled by an operational amplifier which is responsive to a reference voltage and to the amplified output signal of the power combiner such that the signal in the channel provided with the phase shifter operates to limit the efficiency of the power combiner to maintain a power combiner output signal of constant power with respect to the reference voltage.
