Patent number: 8269582Abstract: 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.Type: GrantFiled: October 30, 2009Date of Patent: September 18, 2012Assignee: Alcatel LucentInventors: Jari M. Taskila, Teppo M. Lukkarila, Andrzej E. Stanek

Patent number: 8008994Abstract: 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.Type: GrantFiled: May 1, 2009Date of Patent: August 30, 2011Assignee: Alcatel LucentInventors: Raja K. Reddy, Yin-Shing Chong, Teppo M. Lukkarila, Michael Joseph Adkins

Patent number: 7777598Abstract: A combline filter has a ceramic resonator disposed inside at least one cavity wall. Because the resonator is implemented as a hollow rod, a tuning element may be inserted into an opening on the top of the rod to tune its frequency. A mounting element, inserted into an opening on the bottom of the rod secures its position inside a cavity resonator. Instead of soldering the resonator to the filter's walls, the resonator is supported above a bottom or side wall of the cavity resonator.Type: GrantFiled: April 14, 2008Date of Patent: August 17, 2010Assignee: Radio Frequency Systems, Inc.Inventors: Hamid Reza Salehi, Teppo M. Lukkarila
