Abstract
An impedance matching coaxial adaptor for use with magnetron power sources having output coaxial probes includes an outer cylindrical housing disposed around a cylindrical inner housing. The inner housing is disposed along a common axis of the outer housing and includes a bore disposed within a first end of the inner housing for receiving an antenna-type probe element of a magnetron power source. The coaxial adaptor allow a magnetron source normally having an output probe for radiating into a waveguide to be used with a coaxial output.

A magnetron coaxial adaptor, comprising:
- a cylindrical member having a first end with an opening and a bore extending into said member from said first end and a plurality of longitudinal slots disposed through a portion of said first end to provide a plurality of finger members and a second end of said cylindrical member coupled to a center conductor of a coaxial connector;
- a housing being coaxial with and electrically insulated from said cylindrical member, said housing having an end portion coupled to an outer conductor of said coaxial connector;
- and
- a metal cap being secured to an end of an output probe of a magnetron source;
- and
- said metal cap being disposed with said bore and secured to said cylindrical member by said finger members.
A magnetron output circuit comprising:
- a magnetron output antenna;
- a cylindrical member having a first end with an opening and a bore extending into said member from said first end and a plurality of longitudinal slots disposed through a portion of said first end to provide a plurality of finger members, and a second end of said cylindrical member coupled to a center conductor of a coaxial connector;
- a cylindrical housing being coaxial with and electrically insulated from said cylindrical member, said housing having an end portion coupled to an outer conductor of said coaxial connector;
- a metal cap being secured to an end of said magnetron output antenna;
