    摘要: An acoustic wave device includes: a support substrate; a piezoelectric substrate bonded to the support substrate; a first acoustic wave element formed on the piezoelectric substrate; a frame formed on the support substrate to surround the first acoustic wave element; and a substrate formed on the frame so that a cavity to which the first acoustic wave element is exposed is formed above the piezoelectric substrate, wherein a difference in linear expansion coefficient between the support substrate and the substrate in a first direction in a surface direction of the piezoelectric substrate is less than a difference in linear expansion coefficient between the support substrate and the piezoelectric substrate in the first direction, and the piezoelectric substrate remains in a region where the first acoustic wave element is formed and is removed in a region where the frame is formed.

    摘要: A SAW filter assembly module comprising a plurality of series in-line SAW filter devices and effective to provide substantial isolation of output from input of the module. Separate isolated conductive ground areas are applied to the surface of an insulative substrate upon which the SAW filter devices are placed with a portion of certain areas extending to a terminal side of the substrate and each SAW device is electrically connected to a respective conductive ground area. A separate inter-SAW ground area is provided between each set of device ground areas. A conductive input area of a first SAW filter is located most distant from the conductive output area of a subsequent SAW filter with the plurality of conductive ground areas located therebetween to increase selectivity. A conductive shield is secured to and electrically connected to a ground area between the SAW filter devices and is positioned to block radiative signals between the devices. A shunt inductor is connected between the inter-SAW ground area and in inter-SAW signal path conductive area to increase selectivity with low insertion loss. Bent wire straps, of flat or other essentially non-cylindrical cross-section may be used to make electrical connections between the electrodes of the transducers of each SAW to the appropriate respective conductive areas of the substrate. An insulative cover is positioned over the filter assembly module with portions of the conductive areas extending thereunder toward the terminal side of the substrate.

    摘要: A surface acoustic wave resonator includes an IDT that is disposed on a quartz crystal substrate of Euler angles (−1.5°≦φ≦1.5°, 117°≦θ≦142°, ψ) and excites a surface acoustic wave resonant in an upper part of a stop-band of the IDT, and inter-electrode finger grooves that are acquired by depressing the substrate located between electrode fingers configuring the IDT. The wavelength of the surface acoustic wave, the depth of the inter-electrode finger grooves, the line occupancy ratio of the IDT, and the film thickness of the electrode fingers of the IDT are set in correspondence with one another.
