Abstract: A waveguide circulator comprising at least three waveguide arms intersecting at a junction, wherein the junction has an upper inner surface and a lower inner surface; and a ferrite element positioned within a recess formed within one of the upper inner surface and the lower inner surface of the junction, the ferrite element including a first portion that projects into the junction and a second portion that extends into the recess. A projection extends from an upper outer surface of the junction opposite the upper inner surface of the junction, the projection being positioned opposite the recess formed on the upper inner surface of the junction. In use, the ferrite element is magnetized by applying a magnetic field thereto using a magnet or electromagnet shaped for matingly engaging the projection. A method for manufacturing a waveguide circulator of the type described above is also provided.

Abstract: A waveguide circulator comprising at least three waveguide arms intersecting at a junction, at least one ferrite element positioned within the junction, an impedance transformer and a recessed transformer. At least a portion of each of the at least three waveguide arms and the junction define a first wall and a second wall that are positioned in an opposing relationship. The impedance transformer is positioned in proximity to the at least one ferrite element and projects from the first wall. The recessed transformer is positioned in proximity to the impedance transformer and is recessed within the first wall.
