摘　　要：主要对高温超导滤波器在国内、外应用现状进行分析。在高温超导滤波器的制备上,对现流行的两种衬底MgO基片和LaA lO3基片制备的超导膜所制作的C波段高温超导滤波器的性能进行分析比较。经多次实验测试,实际曲线结果表明:MgO基片制备的超导膜所制作的C波段高温超导滤波器,比LaA lO3基片制备的超导膜所制作的C波段高温超导滤波器在性能和制备上具有优势,便于生产。对滤波器所用制冷器的制冷量进行了计算,计算结果表明可用小型制冷机。HTS filters＇ application actualities are shown in this paper. Presently, HTS filters are mainly built upon the superconducting films with substrate of MgO and LaAlO3. In the paper two kind of C - band HTS filters＇specifications comparison are presented. Test curves suggest that C - band HTS filters with MgO substrate have much advantage in specification and manufacture than ones with LaAlO3 substrate. Refrigerating capacity of eryo - cooler required by HTS filters is also calculated, and its results present that miniature cooler is enough to cool HTS filters.
