Abstract:
1. A circulator/isolator assembly, comprising: a first magnetic substrate having a first surface and a second surface and a first ground plane formed on the first surface; a single dielectric layer disposed adjacent the first magnetic substrate, the dielectric layer comprising a multi-port junction circuit coupled to a plurality of RF transmission traces disposed on a first side of the dielectric layer, one of the traces forming an input port and a different one of said traces forming an output port, and a ground plane disposed on a second side of the dielectric layer; and a first magnet disposed proximate the multi-port junction circuit of the dielectric layer, such that the first magnet excites a circular, unidirectional magnetic flux field in the first magnetic substrate that limits electromagnetic wave propagation to a single direction of the multi-port circuit junction circuit.
