Patent ID: 7999436

Claim:
An electroacoustic component configured to operate with guided bulk acoustic waves, comprising: a substrate comprising monocrystalline LiNbO 3 , an additional substrate; a metal layer on the substrate, the metal layer comprising electrodes for exciting an acoustic wave with a wavelength λ o ; and an intermediate layer between the metal layer and the additional substrate; wherein: the metal layer is between the substrate and the intermediate layer; a first Euler angle λ of the monocrystalline LiNbO 3 is: λ≈0°, a second Euler angle μ of the monocrystalline LiNbO 3 is: − 74 °≦μ≦−52°, a third Euler angle θ of the monocrystalline LiNbO 3 is: θ≈0°; and the thickness of the intermediate layer is between 20% and 200% relative to the wavelength λ 0 .
