Abstract
A resonator is described including: a first part of a metal cavity; a first ring extending from the first part of the metal cavity, wherein at least part of an external surface of the first supporting ring is coated with a first metal coating that provides an electrical connection to the metal cavity; a second part of the metal cavity; and a ceramic ring extending from the second part of the metal cavity. At least part of an external surface of the ceramic ring is coated with a second metal coating that provides an electrical connection to the metal cavity, wherein the first and second parts are mounted to form the metal cavity such that the first ring and the ceramic ring partially overlap such that at least part of the ceramic ring is between at least parts of the first and second metal coatings.
Claims20
A resonator, comprising:
- a first part of a metal cavity;
- a first ring extending from the first part of the metal cavity, wherein at least part of an external surface of the first ring is coated with a first metal coating that provides an electrical connection to the metal cavity;
- a second part of the metal cavity;
- and
- a ceramic ring extending from the second part of the metal cavity, wherein at least part of an external surface of the ceramic ring is coated with a second metal coating that provides an electrical connection to the metal cavity;
- wherein the first part of the metal cavity and the second part of the metal cavity are mounted to form the metal cavity such that the first ring and the ceramic ring partially overlap such that at least part of the ceramic ring is between at least part of the first metal coating and at least part of the second metal coating;
- and
- wherein the first ring extends to make contact with the second part of the metal cavity.
A method, comprising:
- forming a metal cavity with attaching a first part of the metal cavity to a second part of the metal cavity such that a first ring and a ceramic ring of the metal cavity partially overlap such that at least part of the ceramic ring is between at least part of a first metal coating and at least part of a second metal coating, wherein:
- the first ring extends from one of the first part of the metal cavity and the ceramic ring extends from the second part of the metal cavity, wherein the first ring extends to make contact with the second part of the metal cavity;
- the first ring comprises an external surface that is at least partially coated with the first metal coating, wherein, in use, the first metal coating provides an electrical connection to the metal cavity;
- and
- the ceramic ring comprises an external surface that is at least partially coated with the second metal coating, wherein, in use, the second metal coating provides an electrical connection to the metal cavity.
