摘　　要：设计了一种Ka波段11.25°数字移相器。采用一前一后加载支线的方式,在Ka波段内研制出11.25°数字移相器。该移相器在30～31GHz工作频带内,驻波比小于1.65,插入损耗小于3dB,固定相移11.25°,相位精度达到±3°。A new technique for designing millimeter-wave 11.25° digital phase shifter circuit is presented. The proposed phase shifter was fabricated using a tandem stubs phase shifter for 11.25° at Ka-band. In the operating frequency from 30 GHz to 31 GHz, the VSWR of the phase shifter is less than 1.65, the insertion loss is less than 3 dB, the phase shift is fixed around 11.25° and its accuracy is up to ±3°.
