Abstract
An improved surface acoustic wave device that utilizes M electrodes per each N transduction length(s) of a transducer that produces a desired net internal distributed reflectivity in both magnitude and phase. Two of the transducers can be made placed on a single substrate and be unidirectional and caused to radiate towards each other to form a filter. A resonator, a delay line, or the like can also be formed.
