FIELD: radio electronics. SUBSTANCE: microwave phase-shift keyer incorporating input divider and output adder with equal-electric-length channels provided with adjustable attenuator inserted inbetween has its input divider made with mirror symmetry of arms. This property is typical of divider whose output arms are made in the form of +90 and -90 deg. twists of rectangular waveguides and also magnetron with number of cavities multiple of 4 and with two orthogonal planes of symmetry. EFFECT: improved design. 3 cl, 6 dwg
