摘　　要：基于改变射频信号在传输过程中的相移的目的。采用环形正交90°分支线耦合器实现较宽工作带宽,变容二极管获得较大的移相范围。通过ADS2011仿真设计了一种用于Ku波段的反射型模拟移相器,其工作频段为17.7～19.2 GHz,工作带宽1.5 GHz,插入损耗小于3 dB。最终设计出一款最大移相量为160°的连续可调的压控模拟移相器。It is based on the purpose of changing the phase shift of the radio frequency signal during transmission.The phase shifter based on 90.directional coupler and parallel variable capacitanced diodes（VCD）achieves matching circuits and shift phase. A Ku-band broadband analog phase shifter is simulated and designed by using ADS2011.Its operating frequency range is from 17.7～19.2 GHz,and the operating bandwidth is 1.5 GHz. finally,a kind of analog phase shifter with maxmum phase shifting capability of 160°by continuously adjusting the voltage has been laid out.
