ACOUSTIC WAVE DEVICE: abstract simplified (18204979)

• This abstract for appeared for patent application number 18204979 Titled 'ACOUSTIC WAVE DEVICE'

Simplified Explanation

The abstract describes an acoustic wave device that consists of several layers including a support substrate, a piezoelectric layer, an energy confining layer, and two resonators. The piezoelectric layer is made of either lithium niobate or lithium tantalate and has a first principal surface. The energy confining layer is located between the support substrate and the piezoelectric layer. Each resonator has a pair of electrodes attached to the first principal surface of the piezoelectric layer. The first resonator generates a specific type of wave called a thickness-shear mode bulk wave, while the second resonator generates a different type of wave.

Original Abstract Submitted

An acoustic wave device includes a support substrate, a piezoelectric layer, an energy confining layer, a first resonator, and a second resonator. The piezoelectric layer includes a first principal surface and includes lithium niobate or lithium tantalate. The energy confining layer is provided between the support substrate and the piezoelectric layer. Each of the first resonator and the second resonator includes at least one pair of a first electrode and a second electrode provided to the first principal surface of the piezoelectric layer. The first resonator is structured to generate a thickness-shear mode bulk wave, and the second resonator is structured to generate a wave other than a thickness-shear mode bulk wave.
