Mixed non-uniform width/evanescent mode ceramic resonator waveguide filter with wide spurious free bandwidth

Abstract

This paper presents a method to improve the spurious performance of integrated ceramic waveguide filters. Non-uniform width ceramic waveguide resonator and evanescent mode ceramic resonators are employed together to the resonant frequencies of higher order modes. The proposed designs give 75% improvement in stop band response when compared to uniform width… (More)
