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.
Claims16
A circulator, comprising:
- a) at least three waveguide arms intersecting at a junction, at least a portion of said at least three waveguide arms and said junction defining a first wall and a second wall that are positioned in an opposing relationship;
- b) at least one ferrite element positioned within said junction;
- c) an impedance transformer positioned in proximity to said at least one ferrite element, said at least one impedance transformer projecting from said first wall;
- and
- d) a recessed transformer positioned in proximity to said impedance transformer, said recessed transformer being recessed within said first wall.
A waveguide circulator comprising three waveguide arms each comprising a first wall and a second wall, said three waveguide arms intersecting at a junction that includes at least one ferrite element therein, each of said three waveguide arms comprising:
- i) an impedance transformer projecting from said first wall;
- and
- ii) a recessed transformer that is recessed within said first wall.
A method, comprising:
- a) providing a waveguide circulator comprising:
- i) at least three waveguide arms intersecting at a junction, the at least three waveguide arms and the junction defining a first wall and a second wall that are positioned in an opposing relationship;
- ii) at least one ferrite element positioned within the junction;
- and
- iii) at least one impedance transformer within the waveguide circulator in proximity to the at least one ferrite element, said impedance transformer projecting into the junction;
- b) providing at least one recessed transformer into the first wall of the waveguide circulator.
