UN DISPOSITIVO DE ONDA ACUSTICA PERFECCIONADO.

摘要

An acoustic surface wave device employs a substrate structurally orientated to enhance the propagation of acoustic surface skimming bulk waves. Multiple reflections from opposed end faces of the substrate establish an acoustic surface skimming bulk standing wave at a predetermined frequency. An interdigital transducer couples to the standing wave. A plurality of devices may be intercoupled to provide a bandpass filter.
