Abstract
A phase modulation circuit to provide at an output terminal an output signal controllably shifted from 0.degree. to 360.degree. relative to an input signal provided at an input terminal includes a first 90.degree. coupler connected between the input terminal and second and third 90.degree. couplers, four gain controllable amplifiers, fourth and fifth 90.degree. couplers and an in phase combiner with its output connected to the output terminal. Two of the amplifiers are connected between the second and fourth couplers. The additional amplifiers are connected between the third and fifth couplers. The fourth and fifth couplers are connected to the inputs of the in-phase combiner. The gain through the various amplifiers is adjusted to control the amount of phase shift through the circuit.
