20110102112 | COUPLER FOR TUNING RESONANT CAVITIES - Various exemplary embodiments relate to an improved coupler for resonant cavities and dielectric resonators. The coupler may permit accurate tuning of electromagnetic signals within desired frequency ranges. The coupler may be secured to a movable tuning device by a plurality of securing members. Each securing member may be separate, having no contact with any other securing member. | 05-05-2011 |
20110102110 | TUNING ELEMENT ASSEMBLY AND METHOD FOR RF COMPONENTS - Various exemplary embodiments relate to a tuning element assembly and method for tuning an a radio frequency (RF) component, where the component has one or more walls defining a cavity, with at least one wall having at least one bore hole. A bushing is mounted in the bore hole in the wall, and a tuning element is slidably mounted and received in the bushing so that the tuning element projects inwardly through the bushing and into the cavity and is axially adjustable. A method of tuning an RF component also includes providing a bushing mounted in a bore in a wall of the RF component, sliding a tuning element that is slidably mounted and received in the bushing so that the tuning element projects inwardly through the bushing and into the cavity by a distance varying according to the sliding of the tuning element, monitoring a performance characteristic of the RF component, and releasing the tuning element so that a desired performance characteristic is achieved. | 05-05-2011 |
20110102109 | THERMALLY EFFICIENT DIELECTRIC RESONATOR SUPPORT - Various exemplary embodiments relate to a temperature compensation structure for use in a dielectric resonator that permits a support to be thermally efficient in rapidly transferring heat generated by a central puck in the resonator. The temperature compensation structure may have an extension shaped to promote heat from the puck into the support, thereby permitting high power operation of the dielectric resonator without overheating. | 05-05-2011 |
20100277258 | TUNABLE CAPACITIVE INPUT COUPLING - Various exemplary embodiments include a cavity having a tuning assembly with tunable capacitive coupling. The tuning assembly may have a recess having a specified depth, designed for a default magnitude of coupling into the cavity. A sleeve may be fully inserted within the recess to have the structure operate at that default coupling magnitude. If a different amount of coupling is desired, the sleeve may be inserted to a particular depth that only includes part of the recess, enabling repeatable tuning of a plurality of cavities. | 11-04-2010 |
