Acoustic wave filter device and duplexer










Image Number 5 for United States Patent #7532090.

In an acoustic wave filter device, first and second longitudinally coupled resonator SAW filters are provided on a piezoelectric substrate. The first and second longitudinally coupled resonator SAW filters are connected in parallel to each other. The first and second longitudinally coupled resonator SAW filters are withdrawal-weighted. The withdrawal weighting in at least the longitudinally coupled resonator SAW filter is different from the withdrawal weighting in the other longitudinally coupled resonator SAW filter.
