本文综述了我国高温超导滤波器的设计和应用的最新进展。由于高质量的双面薄膜是高温超导滤波器的基础，本文首先介绍了各种物理和化学方法制备高温超导薄膜的研究进展。在过去的十年中，中国已经设计了数百种高温超导滤波器，具有优异的性能，例如，0.05最小插入损耗为-23dB，回波损耗为-110dB，带外抑制为-110dB，带边斜率为220 dB/MHz。耦合矩阵提取方法、宽阻带带通滤波器、线性相位滤波器、多路复用器、多带多模滤波器以及可调谐滤波器等。还将审查在移动的通信基站、气象雷达、深空探测和卫星技术方面的应用。
Recent developments in China for the design and application of high temperature superconducting (HTS) filters are reviewed. Progress in fabrication of HTS thin films with various physical and chemical methods are introduced first, since high quality double-sided thin films provide the groundwork for filters. In the past decade, hundreds of HTS filters have been designed in China with excellent performance, e.g., 0.05 dB minimum insertion loss, -23 dB return loss, -110 dB out-of-band rejection and 220 dB/MHz band-edge slope, etc. Novel design methods, i.e., coupling matrix extracting method, bandpass filters with wide stop band, linear phase filters, multiplexers, multi-band and multi-mode filters as well as tunable filters will be discussed in detail. Applications to mobile communication base stations, meteorological radar, deep space detection and satellite technology will be also reviewed.
