Abstract :
An active passband microwave filter consisting of a magnetostatic wave (MSW) delay line and microwave amplifier has been developed and tested. A narrow passband of 120 kHz was obtained at the S/C-band corresponding to a quality factor Q of ~40 000. The frequency response characteristics are presented
