摘　　要：高温超导滤波器具有带内插入损耗小、带边陡峭、带外抑制性好等优势,可以有效提高通信系统的抗干扰性能,节约频率资源。谐振器是实现高温超导滤波器的重要单元。本文给出了一款新型谐振器,该谐振器结构紧凑、调节方便,并且使用这种谐振器设计了一款十二阶的窄带低频高温超导滤波器。High temperature superconducting （HTS） filter has small passband insertion loss, steep edges and high out-of-band rejection, which can improve the performance of communication system interference effectively and save the frequency resources. The resonator is the most important part in designing HTS filter. In this paper, a hew type of resonator is suggested, which has a compact structure and easy to adjust. A 12 order narrowband and low-frequency HTS filter is realized.
