description The fishtail wave filter comprises a filter shell, an installation plate is fixedly installed at the bottom end of the filter shell, sound absorption plates are fixedly installed on the two sides of the inner wall of the filter shell, and a piezoelectric substrate is fixedly installed in the middle of the inner wall of the filter shell. The fishtail wave filter comprises a filter shell, a piezoelectric substrate is fixedly mounted on the filter shell, a transmitting transducer located on one side of the piezoelectric substrate is fixedly mounted on the filter shell, a receiving transducer located on the other side of the piezoelectric substrate is fixedly mounted on the filter shell, an etching groove is formed in the middle of the piezoelectric substrate, and input connectors are fixedly mounted at the top ends of the two sides of the filter shell. An S-shaped curve is etched on a silver coating of a piezoelectric ceramic piece to form an etching groove, the etching groove is divided into two parts which are
