Abstract : This document describes a wide-band ferrite limiter for operation in the microwave frequency range comprised of a plurality of intercoupled dielectric resonators having a long, thin ferrite rod passing through the longitudinal central axis of the dielectric resonant structure. Broadband operation is achieved by the proximity coupling of the dielectric resonators while the ferrite rod provides an optimized ferrite geometry which serves to increase the dynamic range and also to decrease the critical threshold field. A DC field of magnetization is additionally provided along the longitudinal central axis which with the availability of light-weight small rare earth magnets allows the limiter to be magnetized in such a fashion that a very compact device is achieved thereby.
