Design of Ultra-Wideband Tunable Band-Exclusion Filters (BEFs) on Magnetostatic Waves (MSWs) in Centimetric Frequency Band

Presented in this paper are the results of BEF design on MSWs in cm band with stop band not less than 800 MHz at the level of minus 40 dB. Factors, which influence stop band width, have been analyzed. Different methods for ultra-wideband BEFs design on MSWs have been examined. Characteristics of BEFs designed are presented.
