ABSTRACT:
A surface acoustic wave (SAW) device includes a SAW element disposed on a printed circuit. The printed circuit has an insulation substrate having input and output wiring conductors and input side and output side grounding conductors formed thereon. Interdigital transducers of the SAW element are connected to the input and output wiring conductors. The input side grounding conductors and the output side grounding conductors are disposed apart from each other with an isolation gap inbetween, thereby obtaining desirable filtering characteristics by suppressing undesirable coupling between input side and output side caused by a feed through electromagnetic wave.
