Algorithm for adaptive compensation of intermodulation distortion in microwave power amplifiers

There is a controversial task of reconciling high output power, energy and spectral efficiency with low intermodulation distortion (IMD) in microwave power amplifiers (PA) for mobile and satellite communication systems and other applications. Adaptive predistortion linearizer (Lin) plugged into the PA input contains vector modulator with integrated computing device (Digital Signal Processor - DSP) that removes the controversy and adapts to changes in the environment.
