Abstract
An adjustable surface acoustic wave (SAW) transducer is fabricated on a piezoelectric substrate. The adjustable SAW transducer includes a plurality of SAW interdigital transducer (IDT) fingers disposed on the substrate. Miniature switches are used to provide a plurality of interconnection patterns between the SAW IDT fingers such that a plurality of SAW characteristics can be generated from a single set of SAW IDT fingers.
