摘要： A surface acoustic wave filter comprised of a plurality of surface acoustic wave resonators having different resonance frequencies, the filter comprising a substrate made of lithium niobate, comb electrodes (1201 and 1202) formed on the substrate, and a thin dielectric film covering the comb electrodes (1201 and 1202), wherein the surface acoustic wave resonator having a lower resonance frequency is formed to have a metallization ratio larger than a metallization ratio of the surface acoustic wave resonator having a higher resonance frequency, thereby providing the surface acoustic wave filter and an antenna duplexer featuring superior characteristics with insignificant ripples while suppressing spurious responses of the surface acoustic wave resonators.

摘要： The elastic wave device of the present invention has an piezoelectric substrate; a first dielectric layer disposed on the piezoelectric substrate; a second dielectric layer disposed on the first dielectric layer; and an acoustical layer on the second dielectric layer. Determining each film thickness of the first and the second dielectric layers provides advantageous effects. That is, energy of an SH wave as a main wave is confined in the boundary between the piezoelectric substrate and the first dielectric layer, and at the same time, an SV wave is suppressed as an unwanted wave. The device allows the SV wave—whose displacement distribution is similar to that of Stoneley wave—to have displacement distribution on the upper surface of the second dielectric layer and to be suppressed by the acoustical layer disposed on the second dielectric layer.

摘要： A current control circuit (5) recognizes whether or not a transmission signal is transmitted based on a control signal outputted from a transmission signal control circuit (4). When the transmission signal is transmitted, the current control circuit (5) controls a current flowing into a reception circuit (3) in accordance with control information representing any of at least two modes where the transmission signal is transmitted. When no transmission signal is transmitted, the current control circuit (5) controls the current flowing into the reception circuit (3) in accordance with control information representing a mode where no transmission signal is transmitted.

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： An acoustic wave filter includes a first IDT electrode, a second IDT electrode, and a third IDT electrode. The first IDT electrode includes a first signal electrode finger connected to the unbalanced terminal, and a first ground electrode finger. The second IDT electrode includes a second signal electrode finger connected to a first balanced terminal, and a second ground electrode finger. The third IDT electrode includes a third signal electrode finger connected to the second balanced terminal, and a third ground electrode finger. A dummy electrode finger connected neither to the unbalanced terminal nor to the ground is provided on the second IDT electrode side in the first IDT electrode. Thus, the degree of balance between balanced terminals can be improved.
