摘　　要：电控快速开关环行器属非均匀磁化场激励器件,如采用设计常规环行器的均匀磁化场方法误差很大,该文介绍了基于软件Maxwell 3D和HFSS的混合有限元方法来设计X波段电控快速开关环行器的过程。研制的器件性能经测试为:以10 GHz为中心约1.3 GHz频带内,插损不大于0.3 dB,隔离不小于22 dB,驻波不大于1.2,开关时间约为3μs。Electronically-controlled fast circulating switch operates in inhomogeneous magnetic biasing field. The solution-error of homogeneous magnetic field method for designing general circulator is too big to design the switch. The design of the switch by use of a new hybrid finite element method based on Maxwell 3D and HFSS is presented in this paper. Its performance characteristics are tested to be maximum insertion loss of 0.3 dB, isolation greater than 22 dB over a 1.3 GHz bandwidth centered at 10 GHz, VSWR less than 1.2, while switching time less than 3 μs.
