The invention concerns a tunable cavity resonator that comprises a resonator body ( ) defining a cavity ( ), a tuning plate ( ) whose position with respect to the resonator body ( ) is modifiable and which influences the resonance frequency (&ohgr; ) of the cavity resonator, and an adjustment device ( ) for mechanically changing the position of the tuning plate ( ), which is characterized in that a conversion ratio mechanism ( ) couples the adjustment device ( ) to the tuning plate ( ) in terms of movement and converts a linear excursion (&Dgr;x ) generated by the adjustment device ( ), at a predefined ratio (U), into a reduced linear excursion (&Dgr;x ) that acts on the tuning plate ( ), the conversion ratio mechanism ( ) comprising a first spring element ( ) whose end toward the adjustment device is deflectable with the linear excursion (&Dgr;x ) generated by the adjustment device ( ), and a second spring element ( ) which impinges with an opposing force on the end of the first spring element ( ) remote from the adjustment device.

Tuneable cavity resonator

The object of the invention is a dual-mode band pass filter consisting of resonators each having a spherically shaped dielectric arranged on at least one high-temperature superconductive film, with a shielding housing, which is arranged over the high-temperature superconductive film and which encloses the dielectric, and with a coupling device for coupling the dipole modes, as well as other coupling and tuning elements.
