摘要：

An active passband microwave filter consisting of a magnetostatic wave (MSW) delay line and microwave amplifier has been developed and tasted. A narrow passband of 120kHz was obtained at the S/C-band corresponding to a quality factor Q of similar to 40000. The frequency response characteristics are presented.
