Patent ID: 7019435

Claim:
A surface acoustic wave device comprising: a plurality of surface acoustic wave elements connected in parallel, wherein each of said surface acoustic wave elements comprises: at least three interdigital transducer electrodes, wherein said interdigital transducer electrodes are operable to generate a surface acoustic wave that travels in a propagating direction, and wherein each of said interdigital transducer electrodes is formed of a comb shaped electrode pair; a first reflector electrode disposed at a first side of said interdigital transducer electrodes; and a second reflector electrode disposed at a second side of said interdigital transducer electrodes, wherein said first and second reflector electrodes are disposed in the propagating direction of the surface acoustic wave generated by said interdigital transducer electrodes; one ground connection electrode that connects together a first part of each comb shaped electrode pair forming said interdigital transducer electrodes; and one ground pad that is connected to said ground connection electrode.
