Abstract
The present invention is directed to a piezo-electrically actuated membrane (ex.—a tuner) configured for use with a tunable cavity filter. The piezo-electrically actuated tuner may be formed of printed circuit board materials and may be placed over the cavities of the tunable cavity filter. Further, the piezo-electrically actuated tuner may promote high level performance of the tunable cavity filter, while allowing the tunable cavity filter to be tunable across wide bands.
