利用小型化发夹谐振器，按照切比雪夫模型，设计并制作了中心频率为2.2 GHz、带宽为5 MHz的超导滤波器。用YBCO薄膜在LaAlO_3衬底上制作的谐振器在60K时测得空载Q因子为47000。用Nb薄膜实现了三极和四极原型滤光片。测量的性能在10dBm以下没有明显的退化。《Wiley期刊》，Inc.微波OPT Technol Lett 35：360-362,2002；在线发表在Wiley InterScience(www.intercience.wiley.com)上。DOI 10.1002/MOP.10607
Using miniaturized hairpin resonators and following the Chebychev model, we have designed and fabricated superconducting filters with a centre frequency of 2.2 GHz and a bandwidth of 5 MHz. The measured unloaded Q‐factor of the resonator fabricated on LaAlO3 using YBCO thin film is 47,000 at 60 K. Prototype filters with three and four poles have been realized by using Nb thin films. The measured performances do not show appreciable degradations up to 10 dBm. © 2002 Wiley Periodicals, Inc.
