一种C波段大功率电调滤波器设计
|
摘要
针对电调滤波器失谐和控制精度问题,该文提出了一种保持恒定带宽的耦合机构设计方法,论述了应用三维电磁场仿真软件HFSS协同仿真的过程,分析了运动执行机构软硬件的关键技术,设计了一个C波段、大功率(400 W)的电调滤波器。仿真和实测结果表明,在整个调谐频段内该滤波器的带宽恒定,驻波、抑制度和插入损耗等指标稳定良好。
Aiming at the problem of detuning and control accuracy in the tunable filter, a novel design method of the coupling structure with constant bandwidth is presented in this paper. The co-simulation process of using the 3 D electromagnetic field simulation software HFSS is discussed, and the key software and hardware technologies of the motion actuator mechanism are analyzed. A C-band tunable filter with high power of 400 W is designed. The simulation and measured results show that the bandwidth of the filter is constant in the whole tunable band is nearly constant,and the specifications of the standing wave,suppression and insertion loss are stable and good.
