Abstract :
Receivers are main elements of communication, detecting and warning systems. They are used to detect and measure parameters of signals radiated by different sources of energy. They contain antenna arrays and signal forming circuits. The paper introduces a new design of signal forming circuit composed of quadrate couplers and phase shifters. The method and results of theoretical analysis as well as results of measurements in the range of 2-4 GHz are also presented
