A surface acoustic wave device includes a piezoelectric substrate, a first
and a second interdigital transducers (IDTs) provided on the
piezoelectric substrate. The first IDT includes multiple tracks having
different frequency characteristics that are connected in parallel. The
second IDT includes a normalized electrode pattern. The frequency
characteristic of the multiple tracks is asymmetric to a center frequency
of the SAW filter, substantially flat in a passband when those of the
multiple tracks are overlapped, or complementary in the passband. Thus,
it is possible to provide the surface acoustic wave device having a high
damping property.
