摘　　要：针对复杂电磁环境下射电天文观测接收系统的工程应用需求,我们研制了带外抑制度高的双频段带通滤波器。本文采用1个带通滤波器和2个带阻滤波器串联方式,采用折叠微带线、终端短路、多基片互连电路结构组合。通过理论计算和仿真,完成设计高温超导抗干扰双频段组合滤波器,测试结果和仿真计算结果一致,满足工程应用需求。To eliminate the complex electromagnetic interference in radio astronomical observation,a dual bandpass HTS filter with high out-of-band rejection was developed.It consisted of a bandpass filter and two bandstop filters which were in series each other based on the methods of folding microstrip,terminal short circuit and multi-chip inter-connection.After the calculation and simulation,the results show that the measured results of the filter sample are consistent with ones of the simulation,meeting the requirements well.
