Magnetostatic wave single and multiple stage resonators

Abstract

A review of the design criteria for magnetostatic volume wave band-pass resonating filters will be presented. The prediction of the radiation resistance and of the reactance of microstrip lines coupled to magnetic films in grounded configurations will be used to model straight edge resonators by means of lumped elements. As an application, the performances of tunable single and multiple stage narrow-band filters working at X-band will be evaluated.
