Microwave filters and multichannel divider based on surface magnetostatic waves

Abstract

Consideration to an application of surface magnetostatic waves in ferrite films for the creation of microwave band-pass filters is given. Experimental samples of single-channel filter with insertion losses at the center frequency of less than 2.5 dB are discussed. The filter center frequency and bandwidth can both be tuned independently. Specifications of frequency channelizers are shown.
