基　　金：This work was supported by the Chinese Academy of Sciences (Project No. KJCX2-SW-W01);Commission of Science and Technology of Beijing (Project No. H010410050111). 摘　　要：The first HTS front-end subsystem for wireless base station in China was developed. This demonstration system, which aims at the application in GSM1800 mobile communication base station, consists of a single RF path, i.e. one filter and one LNA, integrated with the pulse tube cooler. The subsystem works at a pass band of 1710-1785 MHz with a gain of 18 dB and at a temperature of 70 K. The accomplishment of such a demonstration subsystem can boost the development of HTS commercial subsystem. 关键词：high temperature superconductor, filter microwave subsystem, mobile communication base station, DEMONSTRATION system.
