Abstract
A circulator comprises a thermally conductive waveguide housing having a plurality of hollow waveguide arms that communicate with a central cavity, with the hollow waveguide arms each having at least one inner sidewall surface that is angled toward the central cavity. A ferrite element is disposed in the central cavity of the waveguide housing. The ferrite element includes a central portion and a plurality of ferrite segments that extend from the central portion. The ferrite segments each protrude into a separate waveguide arm along the at least one inner sidewall surface, with at least one side of each ferrite segment attached to the at least one inner sidewall surface.

A circulator, comprising:
- a thermally conductive waveguide housing having a plurality of hollow waveguide arms that communicate with a central cavity, the hollow waveguide arms each having at least one inner sidewall surface that is angled toward the central cavity;
- and
- a ferrite element disposed in the central cavity of the waveguide housing, the ferrite element including a central portion and a plurality of ferrite segments that extend from the central portion, the ferrite segments each protruding into a separate waveguide arm along the at least one inner sidewall surface, wherein at least one side of each ferrite segment is attached to the at least one inner sidewall surface.
A switching waveguide circulator, comprising:
- a thermally conductive waveguide housing having a plurality of hollow waveguide arms that communicate with a central cavity, the hollow waveguide arms each having at least one inner sidewall surface that is angled toward the central cavity;
- a ferrite element disposed in the central cavity of the waveguide housing, the ferrite element including a central portion and a plurality of ferrite segments that extend from the central portion, the ferrite segments each protruding into a separate waveguide arm along the angled inner sidewall surface, wherein a first side of each ferrite segment is attached to the angled inner sidewall surface;
- a plurality of dielectric transformers each respectively attached to a second side of the ferrite segments opposite from the first side of the ferrite segments and offset from the central portion of the ferrite element, wherein the dielectric transformers protrude into each waveguide arm away from the central cavity;
- and
- a control wire threaded through the ferrite segments and the dielectric transformers;
- wherein the waveguide arms are configured to allow the control wire to exit the central cavity of the waveguide housing between each of the ferrite segments.
