摘要：A surface acoustic wave device for implementing an attenuation characteristic
outside of the pass band and the narrow band characteristics, preferably for use as afilter. The surface acoustic wave device includes a piezoelectric substrate, interdigitaltransducers formed on the piezoelectric substrate, and first and second reflectorsdisposed on the sides of the interdigital transducers. Each of the first and secondreflectors includes an open electrode block with a plurality of electrically independentelectrode fingers, and a short electrode block with a plurality of electrode fingers ofwhich both ends are electrically shorted.
