An acoustically coupled frequency selective radio frequency (RF) device is provided. The device includes a piezoelectric substrate overlain by a plurality of electrodes. The device further includes a pair of RF input terminals at least one of which is electrically connected to at least one of the electrodes, and a pair of output RF terminals, at least one of which is electrically connected to at least one other of the electrodes. At least one of the electrodes is electromechanically reconfigurable between a state in which it is closer to a face of the piezoelectric substrate and at least one state in which it is farther from the face of the piezoelectric substrate.
