Abstract

An L‐band 360° broad‐bandwidth analog phase shifter is designed using varactor. New design equations for expanding bandwidth and improving linear phase‐shift are derived and applied to performances optimization in one circuit. The analog phase shifter is fabricated using MIC and SMT technologies. At 1.2 ∼ 2.0 GHz (L‐band), total phase‐shift of 360° and linear deviation of less than ±2.5% were obtained, and the insertion loss varied less than 2 dB across the band. © 2003 Wiley Periodicals, Inc.
