高温超导微波器件在移动通信中的应用

高温超导微波器件在移动通信基站的应用，蕴涵了巨大的商机。由高温超导滤波器、低噪声前置放大器以及微型制冷机组成的高温超导移动通信基站接收机前端子系统，将给移动通信基站的性能带来了极大的提高。目前，全球已出现一批专业化商业公司。美国已有近2000套高温超导子系统产品在基站做商业运行；欧洲和日本也已完成样机研制。中国科学院物理研究所在2001年初完成了我国第一台高温超导移动通信基站原理性样机。

APPLICATION OF HIGH TEMPERATURE SUPERCONDUCTING MICROWAVE DEVICES IN MOBILE COMMUNICATIONS

The rapid growth of the mobile communication industry has created a significant opportunity for high temperature superconducting(HTS) technology. The HTS base station subsystems composed of filters, low noise amplifiers and cryocoolers have superior characteristics and will bring dramatic improvements for mobile communications. A number of specialized companies have chosen to tie their fates to the development of HTS subsystems in commercial mobile communications. Nearly 2000 HTS subsystem products are currently deployed in the US.Subsystem prototypes in Europe and Japan have also been completed. The first demonstration of an HTS subsystem for mobile communications in China was made by the Institute of Physics, CAS, in early 2001.
