Abstract: A multielement-type piezoelectric filter capable of facilitating assembly and having a reduced size. The base substrate carries a conduction circuit. An input terminal portion, an output terminal portion and a ground terminal portion are formed on a bottom surface of the base substrate and connected to corresponding connection end portions of the conduction circuit. Furthermore, series resonators and parallel resonators are arranged side by side on the base substrate. The lower electrodes of the resonators are connected to the corresponding connection end portions of the conduction circuit via through-holes. In one embodiment, conductive sheets are attached onto exposed upper electrodes of some of the resonators so as to establish a required connection between the upper electrodes. In another embodiment, a common path layer is formed on the upper surface of the base substrate. The upper electrodes of some of the resonators are connected to the common path layer via bonding wires.

Abstract: A ladder-type electric filter device having rubber plates each provided on one or both sides of each of the piezoelectric resonators so as to be brought into resilient contact with the surface of the associated piezoelectric resonator. The rubber plates are shaped so as to not be brought into contact with the respective corner edges of the respective piezoelectric resonators which generate extensive contour vibrations. Thus, the contour vibrations are not suppressed, the insertion loss can be reduced, and a mechanical quality factor Q can be substantially decreased, thereby improving group delay frequency characteristics.
