Abstract
The present invention is directed to a circulator device that includes a housing defining an interior three-dimensional volume. The housing includes a plurality of port openings disposed therein. A gyromagnetic resonator stack is disposed in the housing. The gyromagnetic resonator stack includes a circuit disposed between a first ferrite disk and a second ferrite disk. The first ferrite disk and the second ferrite disks form a pair of ferrite disks having a ferrite disk centroid and a ferrite disk perimeter. The circuit including an asymmetric center resonator having a eccentric region characterized by a predetermined resonator geometry. The circuit further including an impedance matching transmission line structure coupled to an edge of the eccentric region proximate the ferrite disk perimeter and at least one 50 Ohm transmission line structure coupled to a non-eccentric portion of the asymmetric center resonator. Each of the impedance matching transmission line structure and the at least one 50 Ohm transmission line structure extending through corresponding port openings of the plurality of port openings. The impedance matching transmission line structure is characterized by a section geometry and a predetermined matching impedance. The predetermined matching impedance is a function of the section geometry and at least one performance parameter of the device is a function of the predetermined resonator geometry.
