Abstract

Novel designs of directional couplers with input and output isolation for microwave circuits are proposed. The low-loss directional coupler on coupled lines designed with implementation of multilayer liquid crystal polymer (LCP) technology is considered as a component of phase shifters. Using thin layers of LCP circuit material makes it possible to realize a periodical capacitive loading of coupled lines in order to obtain dc isolation between input and outputs, which allows significant simplifying the biasing circuitry of phase shifters and as a result reducing overall size. In line with the experimental results of the coupled line structure the insertion loss does not exceed 0.1 dB in operational frequency band 2.7-3.2 GHz.
