FIELD: radio communication, radiolocation. SUBSTANCE: method consists in generation and in amplification of phase-shift signal of intermediate frequency, in transformation of phase-shift signal of intermediate frequency to signal of operational frequency, in power amplification of signal of operational frequency, in power amplification of signal of operational frequency, in generation of additional signal which frequency is not equal to intermediate frequency. Before amplification phase-shift signal of intermediate frequency is summed with additional signal and after amplification summary signal is limited by amplitude. Device for realization of method includes generator of intermediate frequency signal, key, information recording unit, band-pass filters, intermediate frequency amplifier, mixer, heterodyne, power amplifier, asymmetric filter, amplitude limiter. EFFECT: improved operational efficiency. 4 dwg
