双通道超导滤波器组的研制

A Study of Dual Channel Superconducting Fliter

该文设计了一中等带宽发夹式双通道超导度波器，对其实验结果作了详细的分析，总结了如何抑制发夹超导滤波器表面波寄生通带．该发夹式双通道超导滤波器中心频率为：２．７５ＧＨｚ、３．２５ＧＨｚ，带宽为：５００ＭＨｚ，带内最小插损１．２ｄＢ，带内平坦度±１．５ｄＢ．

In this Paper the expeerments results of a dual channel bandpess superconductor filter,which consisted of hair-pin line,was analysed.Generalized how to restrain the parastical pass-band of the the-pin line bandpass filter.The center frequency of the dial channel superconductor Filter are 2.75GHz and 3.2GHz,the Passband width is 500MHz, the minimum loss is 1.2 dB,and the ripple in the pass-band is ±1.5dB.
