【摘要】：高温超导材料的微波表面电阻比铜等金属小将近3个数量级,所以自从高温超导材料发现以来,人们就开始了高温超导微波滤波器的研究,并研制出了各种各样具有低损耗、高选择性、优异的带内群时延特性等性能优异的高温超导滤波器.与此同时,高温超导滤波器的应用研究也取得长足进步.目前,由高温超导滤波器、微型斯特林制冷机及半导体低噪声放大器等组成的高温超导微波前端子系统已经在移动通信、雷达、深空探测和卫星通信等多个领域获得应用并取得了显著的经济和社会效益.近年来,高温超导滤波器的研究也在不断地向新的方向拓展,在大功率承载能力、多通道器件、可调频率滤波器以及全超导接收机等领域取得显著进展.本文对高温超导滤波器的研究现状和应用进展进行总结,并对高温超导滤波器及微波应用的研究发展趋势进行展望.
[Abstract]:The microwave surface resistance of high temperature superconducting materials is nearly three orders of magnitude smaller than that of copper and other metals. Since the discovery of high temperature superconducting materials, people have begun to study high temperature superconducting microwave filters, and have developed various kinds of microwave filters with low loss. High-selectivity, excellent inter-band group delay characteristics and excellent performance of high-temperature superconducting filters. At the same time, great progress has been made in the application of HTS filters. At present, high-temperature superconducting microwave front-end subsystems composed of high-temperature superconducting filters, miniature Stirling refrigerators and semiconductor low-noise amplifiers have been used for mobile communication, radar, and so on. Many fields such as deep space exploration and satellite communication have been applied, and remarkable economic and social benefits have been obtained. In recent years, the research of HTS filters has been expanding to a new direction, and has made remarkable progress in the fields of high power bearing capacity, multi-channel devices, tunable frequency filters and all-superconducting receivers. In this paper, the research status and application progress of HTS filters are summarized, and the development trends of HTS filters and microwave applications are prospected.
