A nonreciprocal tunable YIG filter in a microstrip configuration has been constructed which makes use of a novel method of generating a circularly polarized field in the plane of a microstrip circuit. Nonreciprocities in excess of 40 dB have been obtained at X band with relatively low insertion loss and VSWR.read more

Nonreciprocal Coupling with Single-Crystal Ferrites
TL;DR: In this article, the construction of a simple X-band waveguide junction, acting as a 4-port resonant circulator, is described, which can be made tunable over the waveguide frequency range, with a bandwidth in the order of 10 Mc, and with values of insertion loss and isolation, which are comparable to those of conventional circulators.
