基于缺陷地技术六位数字移相器的设计
资料介绍
针对传统的数字移相器工作频带窄,插入损耗大等不足,提出了一种利用缺陷地结构的加匹配线的新型开关式移相器设计技术。该开关式移相器包括固定长的主线以及在主线边缘的开路短截线、短路短截线和背面的缺陷地结构。研制了具有2.3GHz~2.5GHz和3.0GHz~3.2GHz两个带通移相器,具有插入损耗小,移相精度高等优点。实际测试特性：六位数字移相器插入损耗低于5.6dB、相移精度小于3.5°、驻波比小于1.4。
Aiming at the narrowband and high loss in conventional digital phase shifrer,the new Defected Ground Structure（DGS）technique for switch phase shifter is presented in this paper.The proposed switch phase shifter consists of a fixed main line and parallel open stubs and DGS structure.The dual frequency 2.3GHz-2.5GHz and 3.0GHz-3.2GHz can be achieved by the proposed structure.Furthermore,the phase shifter is with the lower loss and the high-accuracy.The insert loss is less than 5.6dB,the precision of phase shifter is less than 3.5°and the VSWR is less than 1.4.
