Abstract
A radio frequency (RF) cavity resonator having a resonator chamber and one or more RF coupling loop assemblies is presented. The RF coupling loop assembly has a connector with a first connector interface coupled to an inner conductor and a second connector interface coupled to an outer conductor, the first and second connector interfaces forming a pair when mated, the second connector interface rotatable about a collinear axis of the connector and the first connector interface not rotatable about the collinear axis of the connector; a wire loop coupler; and a bandwidth selection element at least partially coupled to the coupling loop assembly. In response to changing the bandwidth selection setting while the RF cavity resonator is operational, the wire loop changes orientation about the collinear axis of the connector and causes the RF resonator chamber to output an RF carrier signal having a bandwidth of the new bandwidth setting.
