    摘要： An acoustic wave filter having excellent steepness is provided without adding any exterior components or any new manufacturing steps. A plurality of filters (10-1) each having a first resonator (2a-1) placed in a serial arm and having a resonance frequency frs and an anti-resonance frequency fas, and a second resonator (4a-1) placed in a parallel arm and having a resonator frp and an anti-resonance frequency fap are provided on a same substrate, where the resonance frequency frs of the first resonator is higher than the resonance frequency frp of the second resonator; the anti-resonance frequency fas of the first resonator is higher than the anti-resonance frequency fap of the second resonator; and the filters (10-1) are connected in multiple stages. At least one of the filters (10-1) connected in multiple stages has a third resonator (6-1) having a resonance frequency frp and an anti-resonance frequency fap. The third resonator (6-1) is formed on the substrate and connected to the serial arm in parallel with respect to the first resonator (2a-1).

    摘要： A filter includes multiple piezoelectric thin-film resonators each having a substrate, a lower electrode formed on the substrate, a piezoelectric film formed on the lower electrode, and an upper electrode provided on the piezoelectric film so that the upper electrode and the lower electrode face each other across the piezoelectric film. The multiple piezoelectric thin-film resonators include a first resonator in which at least a part of an outer curved portion of the piezoelectric film of the first resonator is located further out than an outer curved portion of a region in which the upper electrode and the lower electrode face each other across the piezoelectric film. The multiple piezoelectric thin-film resonators includes a second resonator in which at least a part of an outer curved portion of the piezoelectric film of the second resonator substantially coincides with an outer curved portion of a region in which the upper electrode and the lower electrode face each other across the piezoelectric film or is further in than the outer curved portion of the region.

    摘要： An antenna duplexer is provided, which can be built with a smaller size and lower height than ever without compromising out-of-band attenuation characteristic and isolation characteristic between a transmit terminal and a receive terminal. The antenna duplexer includes a transmit filter provided between an antenna terminal and the transmit terminal, and a receive filter provided between the antenna terminal and the receive terminal. The filters are enclosed by a package, in which a ground pattern for the receive filter is separated from other ground patterns.
