Abstract
A microwave tuning device is disclosed which utilizes a resonator rod mounted in a housing. One end of the resonator rod is attached, or shorted, to the housing wall and the other end is unattached or open. The open end of the resonator rod has a cylindrical recess and an insulator ring is disposed between the open end of the resonator rod and the cavity wall. A tuning screw is incrementally inserted through the insulator ring and into the cylindrical recess for adjusting the tuning capacitance and thereby the resonant frequency.
