    摘要: An electroacoustic component includes a substrate that includes a quartz single crystal. The quartz single crystal has a first Euler angle λ: −5°≦λ≦5°, a second Euler angle μ, and a third Euler angle θ. A contiguous region of the quartz single crystal has the following vertices Pi(μi, θi): (23°, 20°), (60°, 17°), (110°, 30°), (105°, 42°), (60°, 30°), (23°, 25°).

    摘要: A component working with guided bulk acoustic waves includes a first substrate, a second substrate, and a layer system between the first and second substrates. The layer system includes a metal layer and a dielectric layer. A ratio of the acoustic impedance of the metal layer to the acoustic impedance of the dielectric layer is greater than or equal to 4.5.

    摘要: An electroacoustic component operates with guided acoustic waves and includes a first substrate, a second substrate, a metallic layer and an intermediate layer. The first substrate (S1) is made from a monocrystalline LiTaO3. The metallic layer is arranged between the first substrate and the intermediate layer. The intermediate layer is arranged between the metallic layer and the second substrate. The crystal section of monocrystalline LiTaO3 is chosen such that for the second Euler angle μ: −100°≦μ≦−40° or −160°≦μ≦−130°. For the first Euler angle λ, preferably λ=0° and for the third Euler angle θ, −10°≦θ≦10°.
