  • Abstract
    In the report variants of linearization of the power amplifier on balancing cascades (BK) are presented. Results of modeling and experimental researches of model samples are introduced. Reduction of IMI distortions of signals QAM 64,128,256 with width of signal spectrum 28 MHz on (5...6) dB in the variation range of input powers (4...6) dB is experimentally received. Within the limits of changing of input power (12...13) dB the reduction by IMI is (1...6)A6. By numerical modeling possibility of decreasing by IMI with simultaneous increase of efficiency is shown.
