ABSTRACT:
A surface acoustic wave (SAW) device (300) comprising interdigital transducers (302, 304, 306) combined on acoustic tracks (308, 310). Resonant interdigital transducers (302, 304) are electrically and acoustically coupled in series on a common acoustic track (308) while anti resonant transducer (306) is electrically coupled to the series connection and located on the second acoustic track (310).
