Abstract

Mode type circulators/isolators are formed using a ferrite material which is magnetically biased to form a resonator. To this resonator, matching networks (usually quarter wave impedance transformers) are connected to transform the impedance to a nominal level (usually 50 ohms). To obtain a two-port isolator, the isolation port of the circulator is resistively terminated at the end of the matching network.
