FIELD: radio engineering.
SUBSTANCE: invention can be used for setting of required amplitude-frequency characteristics, phase-frequency variations of phase-shift keyed, amplitude-shift keyed signals, and also amplitude-phase-shift keyed signals in specified frequency band and frequency transformation. Modulator contains radio-frequency signal source, two-pole controlled element operated by low-frequency control signal source, four-pole network made of resistive two-pole networks, load for line amplitude and phase modulated radio-frequency signals with complex conductance values. Parameter values of resistive elements forming resistive four-pole network are specified in such a way as to maintain required phase and transmission coefficient in the first condition and to provide transmission coefficient module in the first condition determining physical realisation of four-pole network, to provide modules and transmission coefficient phase difference in two conditions of controlled element determined by two extreme values of low-frequency control signal which is specified by required mathematical expressions from formula of invention.
EFFECT: provided line signal amplitude and phase manipulation in two conditions of controlled element within wide band.
