Simulation of an analog phase shifter

Abstract

The feature of the phase shifter under study is a set of identical connected cascades in T-scheme. The results of numerical modeling are presented. The studied device is optimized for S-parameters in the frequency range; phase and amplitude characteristics of return loss and insertion loss are investigated. Thus, the possibility of modeling of a microwave module of an analog phase shifter based on a two-port cascade connection, is shown. The results of numerical simulation of multi-cascade analog phase shifters based on the elements with controlled capacity. These experimental frequency characteristics of the phase shifter produced on the basis of numerical modeling results are fully agreed with the calculated data.
