摘要： An acoustic wave device operable as a piston mode wave guide includes electrodes forming an interdigital transducer on a surface of the piezoelectric substrate, wherein each of the plurality of electrodes is defined as having a transversely extending center region and transversely opposing edge regions for guiding an acoustic wave longitudinally through the transducer. A Silicon Oxide overcoat covers the transducer and a Silicon Nitride layer covers the Silicon Oxide overcoat within only the center and edge regions. The thickness of the Silicon Nitride layer is sufficient for providing a frequency modification to the acoustic wave within the center region and is optimized with a positioning of a Titanium strip within each of the opposing edge regions. The Titanium strip reduces the acoustic wave velocity within the edge regions with the velocity in the edge regions being less than the wave velocity within the transducer center region.

摘要： An acoustic wave device includes electrodes carried on a surface of a piezoelectric material and an array of reflective obstacles such that elastic energy resulting from a piezoelectric effect is preferentially directed along a primary wave propagation path. The array of reflective obstacles are positioned generally parallel to the surface of the piezoelectric material and redirect acoustic waves typically reflected in other than a desirable direction to along a desired direction generally along the primary propagation path. The obstacles improve performance for SAW and BAW devices by effecting reflected energy and suppressing spurious modes.

摘要： A SAW filter includes a piezoelectric substrate of a single crystal LiNbO3 and SAW resonators having an electrode thickness ranging from about 8% to about 9% of an acoustic wavelength of a high velocity SAW excited on the surface of the substrate. The piezoelectric substrate has an orientation defined by Euler angles (&lgr;, &mgr;, &thgr;), with angle &lgr; in a range from −5° to +5°, angle &mgr; in a range from about 75° to about 85°, and angle &thgr; in a range from 85° to 95°. A metalization ratio for the resonators ranges from about 0.3 to about 0.9, with resonators in a parallel arm of the filter having a metalization ratio from 1.1-1.4 times larger than the metalization ratio for resonators in the series arm of the filter. Such orientations simultaneously combined with an optimized electrode thickness and optimized metalization ratios provide an improved performance in RF applications.

摘要： A SAW filter includes a piezoelectric substrate of Lithium Niobate or optionally Lithium Tantalate having a thickness of at least twice an acoustic wavelength. The piezoelectric substrate is bonded to a surrogate substrate of a silicon material. The surrogate substrate is characterized by a resisitivity of at least 100 ohm-cm and an expansion coefficient compatible with the piezoelectric substrate. A catalytic bonding film between the piezoelectric substrate and the surrogate substrate is formed from a first catalytic bonding film deposited onto a surface of the piezoelectric substrate and a second catalytic bonding film deposited onto a surface of the surrogate substrate. The piezoelectric substrate is bonded to the surrogate substrate through a compression force sufficient for providing a bonding at a normal temperature.
