Patent ID: 7683731

Claim:
A ferrite waveguide circulator, comprising: a waveguide structure having an internal cavity, the waveguide structure including a plurality of ports extending from the internal cavity; at least one ferrite element disposed in the internal cavity, said ferrite element including at least one leg having a length dimension, a height dimension, and a width dimension, wherein the length dimension is parallel to the direction of propagation of a signal through the leg of the ferrite element, the height dimension and the width dimension are perpendicular to the direction of propagation of a signal through the leg of the ferrite element, and the height dimension is larger than the width dimension, said at least one leg of the ferrite element having at least two side surfaces and one face surface, wherein said side surfaces extend along the length dimension and the height dimension and the face surface extends along the height dimension and the width dimension; and at least one thermally-conductive dielectric attachment affixed to at least one of said side surfaces of the ferrite element.
