Compact resonator filter using the piezoelectric effect.

摘要

The present invention relates to a compact resonator filter using the piezoelectric effect. It consists of an insulating substrate (1) on which there are placed one or more active or passive components (9), at least one vibrating vane (5) excited by the piezoelectric effect, output and input terminals (13), connections (7) connecting the output and input terminals (13) to the component or components (9) and to the vibrating vane (5). The substrate (1) is provided with holes (2) through its main faces (3,4) each hole containing a vibrating vane (5). The substrate (1) is a single piece or consists of an arrangement of layers. <IMAGE>
