Popis: Most commercial degree-two waveguide circulators using gyromagnetic turnstile and post resonators are quarter-wave coupled by metal transformers. The purpose of this short paper is to experimentally describe one post-resonator geometry using a self-jigging, partially dielectric-loaded radial waveguide transformer. The assembly developed in this work has a return loss of 20 dB and an insertion loss of 0.20 dB over a bandwidth of approximately 12% in the WR90 waveguide. © 2003 Wiley Periodicals, Inc.
