高温超导滤波器在航天技术中的应用

A way of the application of high temperature superconductive（HTS）filter in the space is presented,and advantages of the HTS filter used in the space technology field to improve the sensitivity of the receiver, reduce the noise factor of the receiver, decrease the antenna received area, increase the TT&C coverage of spacecrafts, and so on are analyzed. An on\|orbit verification device of the HTS filter is designed in this paper, this device has been successfully used in satellites of China.
