FIELD: radio engineering.
SUBSTANCE: invention can be used for setting of required amplitude-frequency characteristics and phase-frequency variations of phase-shift keyed, amplitude-shift keyed and amplitude-phase-shift keyed signals in specified frequency band and frequency transformation. Radio-frequency signal amplitude and phase modulator contains radio-frequency signal source, two-pole controlled element, four-pole network made of resistive two-pole networks, low-frequency control signal source, load for line amplitude and phase modulated radio-frequency signals with complex conductance. And parameter values of resistive elements forming resistive four-pole network are specified such that to maintain required relations of modules and transmission coefficient phase differences in two conditions of controlled element determined by two extreme values of low-frequency control signal defined by mathematical expressions.
EFFECT: provided line signal amplitude and phase manipulation in two conditions of controlled element within wide band.
