Patent ID: 7696674

Claim:
An electroacoustic component operating with guided bulk acoustic waves, the component comprising: a first substrate made from a monocrystalline LiTaO 3 ; a second substrate; a metallic layer; and an intermediate layer; wherein the metallic layer is arranged between the first substrate and the intermediate layer; wherein the intermediate layer is arranged between the metallic layer and the second substrate; and wherein a crystal section of monocrystalline LiTaO 3 is chosen such that for a first Euler angle λ, λ=0°, for a second Euler angle angle μ: −100°≦μ≦−40° or −160°≦μ≦−130°, and for the third Euler angle θ, −10°≦θ<0°or θ=0° or 0°<θ≦10°; and wherein the electroacoustic components operates with guided bulk acoustic waves.
