METHOD FOR PHASE-SHIFT KEYING AND DEVICE THEREFOR Russian patent published in 2016 - IPC H04L27/18 H03C3/00 

FIELD: wireless communication.

SUBSTANCE: invention relates to radio communication equipment, particularly to phase-difference keyers with double phase-shift keying, and can be used in high-power transmitters in data transmission equipment. Method for phase-shift keying radio signal transmitter is characterised by step change of phase oscillation of carrier frequency keying ratio between preset values of phase, wherein phase change is performed during not less than duration of transient process in complex load, and step phase change is equal to ratio of duration of transient process in composite load to degree of two with degree equal to specified natural number M. Pulse phase-shift keyer comprises a reference oscillation generator, series-connected pulse switching circuit and division into two frequency of their repetition, transistor switch phase keying, connected via decoder with information source, a generator of pulse sequence for changing phase and circuit of logical multiplication.

EFFECT: technical result is reduction of parasitic amplitude and phase modulation of output signal.
