复杂耦合超导滤波器

HTSC Filter with Complex Couplings

从高温超导滤波器小型化带来的复杂耦合出发、研究了复杂耦合分析的方法。用全波分析的滤波器设计手段,从谐振器及谐振器间耦合入手,讨论了各种耦合机理对滤波特性的影响;在结构上,提出滤波器小型化设计方案,并对小型化引入的复杂耦合进行分析。给出了小型化结构及其仿真和实验结果,其实验产品已用于实验接收机系统。

As one of the main properties of miniaturized HTSC filters, the complex couplings of HTSC Filter is proposed, and the analysis method of these complex couplings is studied. As the method, full wave technology is used to design the filter, and the couplings between or in resonators are studied by this method, then the effects to filtering response of these couplings are discussed. From the aspect of structures, the miniaturization procedure of HTSC Filter is under discussion with the complex couplings. There are some miniaturized structures and their simulated and tested results, and the fabricated filters are used in one real communication receiver.
