摘要： A planar Y-junction microwave circulator formed by depositing on a ferrite substrate a metallization pattern consisting of a central resonant disc and three transmission line ports radially extending from the periphery of the disc at junctions spaced apart by 120.degree.. The transmission characteristics of the circulator are controlled by a DC magnetic field which biases the ferrite. Wide-band operation on the order of one octave is achieved by using larger port coupling angles and a smaller disc radius than are conventionally used.

摘要： A rectangular toroid of a substrate material has a ferrite arc plasma sprayed into a channel toroid leaving two faces exposed. An off center aperture receives a drive winding which surrounds one long side of the toroid, the other long side is covered by three co-planar and parallel metal strips, slightly spaced and having ferrite material between the strips and forming a co-planar surface with the metal strips.
