Abstract

Switchable and/or tunable filters, methods of manufacture and design structures are disclosed herein. The method of forming the filters includes forming at least one piezoelectric filter structure comprising a plurality of electrodes formed on a piezoelectric substrate. The method further includes forming a fixed electrode with a plurality of fingers on the piezoelectric substrate. The method further includes forming a moveable electrode with a plurality of fingers over the piezoelectric substrate. The method further includes forming actuators aligned with one or more of the plurality of fingers of the moveable electrode.
