摘要: A surface acoustic wave (SAW) filter includes a piezoelectric substrate. resin pattern having permittivity less than that of the substrate and first second conductor patterns are disposed on The defines two one-terminal-pair SAW resonators longitudinally coupled resonator filters. portion wiring traces different potentials. Portions facing each other in plan view pattern.
