摘要： An acoustic wave duplexer includes a piezoelectric substrate, a first filter and a second filter whose center frequency is higher than that of the first filter, the first and second filters being provided on the piezoelectric substrate. The first filter is structured as a ladder type. A resonator positioned nearest to an antenna terminal out of series-arm resonators is designated as a first resonator. A pitch of a comb-shaped electrode structuring the first resonator is set such that a bulk wave emission frequency of the first resonator becomes higher than a passband of the second filter.

摘要： The antenna sharing device has a first elastic-wave filter for passing signals of a first frequency passband and a second elastic-wave filter for passing signals of a second frequency passband higher than the first frequency passband. The first elastic-wave filter is a ladder-type filter including a first series resonator and a second series resonator having an antiresonant frequency point higher than that of the first series resonator. The first series resonator has a first IDT electrode and a first dielectric film covering the electrode. The second series resonator has a second IDT electrode and a second dielectric film covering the electrode. The first and the second dielectric films have a first projection and a second projection, respectively, so as to be formed above the electrode fingers of each IDT electrode. The cross-sectional area of the first projection of the first series resonator is larger than that of the second projection of the second series resonator in the excitation direction of the elastic wave. The structure satisfies both of steepness in a crossband and low loss in a passband.

摘要： An acoustic wave resonator includes a piezoelectric body, an IDT electrode for exciting an acoustic wave with wavelength λ, and a dielectric thin film provided so as to cover the IDT electrode. The IDT electrode includes a bus bar electrode region, a dummy electrode region, and an IDT cross region in order from outside. The film thickness of the dielectric thin film above at least one of the bus bar electrode region and the dummy electrode region is smaller than that above the IDT cross region by 0.1λ to 0.25λ. This configuration provides an acoustic wave resonator that reduces transverse-mode spurious emission.
