发明名称 Surface acoustic wave filter
摘要 A surface acoustic wave (SAW) filter includes a plurality of interdigital transducers located on a piezoelectric substrate along a surface wave propagation direction, at least a single one-port SAW resonator being connected in parallel with an output side of the SAW filter, while the resonance frequency (f0) of the SAW resonator is set in frequency region level which is lower than the pass band of the SAW filter.
