摘要： The microwave frequency characteristics of a cavity having a center conducting element and conducting cavity are modified by changing the length of the center conducting element. The resonating structure is comprised of a coaxial member providing the principal resonating surfaces. One end of the coaxial member is coupled to a wall of the cavity surrounding the center conducting member with provision for access to the interior of the center conducting member from a position exterior to the cavity. The second end of the center conducting element is free. In addition, the second end of the resonating element has threads fabricated on an interior surface and a self-locking insert positioned in the threaded portion. A threaded rod is inserted through the self-locking insert and extends beyond the center conducting element into the cavity. The threaded rod has a structure on the end remaining inside the center conducting element that permits a tuning instrument, inserted from a position exterior to the cavity, to rotate the threaded rod against the force of the self-locking insert and, consequently vary the length of the rod extending beyond the cylindrical member.
