A switched line microwave digital phase shifter and a hybrid coupler phase shifter using PIN diodes which are operated at center frequencies from 14GHz to 14.5GHz are presented. The former is able to realize 180 degree phase shift and the latter is able to realize 11.25 degree phase shift. The phase shifters are designed to implement on a microstrip circuit type. Both of the two phase shifters can...
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...
