STATE OF THE ART OF RECTANGULAR WAVEGUIDE RESONANCE ISOLATORS AND DIFFERENTIAL PHASE SHIFT CIRCULATORS,
Abstract
This report describes briefly the classical theory of operation of both the ferrite rectangular waveguide resonance isolator and the ferrite differential phase shift circulator. Theoretical expressions and related graphs are presented which are useful in making a comparative evaluation of ferromagnetic materials and predicting the approximate performance of one material when the performance of another is known. Some of the variable properties of useful ferrite and garnet materials are discussed and presented in graphical and tabulated form. Typical state-of-the-art characteristics of rectangular waveguide resonance isolators and differential phase shift circulators are tabulated as a function of frequency. A brief discussion is given relative to the development of the first low-frequency, high-power, 3-port waveguide circulator. (Author)
