Microwave magnetoelectric devices

Abstract

Tunable microwave magnetoelectric devices based on layered ferrite-ferroelectric structures are described. The theory and experiment for attenuator, band-pass filter and phase shifter are presented. Tunability of the ME devices characteristics can be executed by application of an electric field. This electric tuning is relatively fast and is not power-consuming. The attenuator insertion losses vary from 26dB to 2dB at frequency 7251MHz. The tuning range of 25MHz of band-pass filter at frequency 7360MHz was obtained. A maximum phase shift of 30-40 degree at the frequency region 6-9 GHz was obtained. Copyright © 2012 A. S. Tatarenko and M. I. Bichurin.
