Abstract
An acoustic surface wave device having a substrate of a material capable of propagating acoustic surface wave energy. At least one electro-acoustic transducer coupled to a region of a surface of the substrate. The transducer has a first and a second bus bar positioned parallel and a distance from each other. A plurality of electrodes extend from each bus bar. The electrodes from the first bus bar are opposite to the electrodes of the second bus bar with the electrodes from one of the bus bars being forked and surrounding the electrode located in an opposite relationship thereto, thus, reducing substantially any synchronous reflections.
