Abstract
In this study a low-cost 6-bit P-I-N phase shifter with fast switching time, low RF attenuation variation over phase change, and low switching power is described. These unique characteristics make it ideal for S band beam steering applications. The circuit made in microstrip line, consists of six cells in cascade, giving phase shifts of 5.625, 11.25, 22.5, 45, 90, and 180o, respectively. Each section consists of a 3dB coupler loaded by phase shifting networks. Novel phase shifting networks result in a wide bandwidth, low loss and, ultra low phase error.
