Abstract
A resonant cavity filter includes a housing having a resonator therein, and a tuning element including an elongated pin member having a conductive outer surface. The tuning element is mounted for insertion of the elongated pin member into an interior of the resonator. The conductive outer surface includes a contact portion by which the elongated pin member is secured in a desired position to adjust a frequency response of the resonant cavity filter, where the contact portion is free of threading.
