摘要
In this paper, a Ku band seven bit microwave digital phase shifter using PIN diodes is designed based on simulation software ADS(Advanced Design Simulation). The circuit consists of four bits realized by hybrid coupler phase shifters and three bits realized by switched line phase shifters. All of seven bits take proper measures to obtain flat phase shift. The phase shifter is designed to implement on a microstrip circuit type and to operate at frequencies from 14GHz to 14.5GHz. Seven bit phase shifter in this work can achieve 128 states. The simulation results show that at all the 128 states the design is effectual, including slight deviation of phase shift and fine insertion loss as well as VSWR.
