Plural supply path acoustic surface wave device

摘要

An acoustic surface wave device wherein an interdigital transducer is provided which includes interdigitated electrodes of narrow width and fine spacing extending from parallel bus bars. Means are provided electrically to interconnect members of a set of electrodes at a location spaced from the bus bar from which they extend to provide multiple current paths between the bus bar and metallization elements forming the electrodes. In one embodiment, apodized electrodes are interconnected adjacent ends of electrodes of the opposite set. In split electrode transducers, the electrodes of each pair are also interconnected at the ends opposite the associated bus bar.
