This invention relates to surface acoustic wave withdrawal weighted interdigital transducers and in particular to an electrode thinning technique that achieves mass loading reductions in such devices. Surface acoustic wave SAW technology has become increasingly attractive for various signal processing applications, primarily because SAW devices can be fabricated to be compact, lightweight, and reliable using well established planar techniques. Many analog filter functions, not easily synthesized with classical techniques, can be realized with SAW transversal filters.
