Abstract

The present invention relates to a coaxial cavity resonator having walls delimiting cavity, and one resonator body having a conductive rod with a first end being in short circuit relation to a first wall of the cavity walls. the first end a cross-sectional area. The resonator further includes a first conductive supportive plate with a first side connected to the first end of each rod. The first side has a larger area than the cross-sectional area of the first end of the rod and a second side, opposite the first side, fo the supportive plate is electrically connected to the first wall. A retainer is provided in the first cavity wall to guide the supportive plate, and an attachment is provided to secure the first supportive plate to the retainer. The invention also relates to a filter and a use of a resonator component in a filter.
