摘要： A surface acoustic wave device comprises a pair of multiple-electrode surface acoustic wave elements that are mirror-symmetrically arranged and disposed on a piezoelectric substrate. Each of the multiple-electrode surface acoustic wave elements comprises a plurality of input/output inter-digital transducers and connected inter-digital transducers. The number of the input/output inter-digital transducers is equal to or smaller by one, than the number of the connected inter-digital transducers, so that insertion loss of the surface acoustic wave device can be reduced without increasing the size of the device.
