| 摘 要： | 基于Sapph ire基片的双面YBCO超导薄膜,设计了应用于第三代移动通信系统—WCDMA移动通信系统的8节和12节高温超导滤波器。滤波器采用了Ω型谐振器,具有结构紧凑、易引入交叉耦合等特点。在引入交叉耦合之后,滤波器频率响应具有准椭圆函数的特性,其带边陡峭度比切比雪夫型滤波器提高了60%以上。

| Abstract: | In this paper,using double-sided YBCO thin film on sapphire substrate,we designed an 8 pole and a 12 pole HTS(high temperature superconducting) filters for WCDMA Mobile Communication System.These filters were made up of Ω type resonators with compact structure.Furthermore,the HTS filters were introduced with cross coupling structures and had quasi-elliptical function response.Therefore,the band-edge steepness of the designed filters was improved by 60%,compared with Chebyshev type filters. |
