发明名称 Surface acoustic wave device
摘要 A includes a non-piezoelectric substrate and a piezoelectric substrate (206) having matched transducers on both opposed surfaces of the piezoelectric substrate (206). The matched transducers being 180 degrees out of phase from one another. The present invention provides for improved coupling due to the new SAW the multilayer transducer topology.
