Abstract

A simple technique for forming multiple metal rings on both sides of a YIG element has been developed to suppress the spurious responses of YIG resonators. By using this resonator, a 10-mm*5-mm*4-mm/sup 3/ two-stage MSW (magnetostatic wave) bandpass filter has been developed. The insertion loss is about 2 dB at 1.9 GHz and the suppression of spurious response is 25 dB. The filter is useful for signal processing in the circuits of portable microwave telecommunication sets because of its compact dimensions and excellent filter characteristics.<>
