  • Patent number: 6153961
    Abstract: A surface acoustic wave element having a cut-out angle from a langasite single crystal and a direction of propagating a surface acoustic wave of (180.degree.+.alpha., 40.degree.+.beta., 20.degree.+.gamma.) in Eulerian angles where .alpha.=-2.degree. to +6.degree., .beta.=-4.degree. to +9.degree., and .gamma.=-1.degree. to +9.degree.; of (0.degree.+.alpha., 140.degree.+.beta., 24.degree.+.gamma.) where .alpha.=-6.degree. to +6.degree., .beta.=-5.degree. to +5.degree., and .gamma.=-5.degree. to +5.degree.; or of (9.degree.+.alpha., 150.degree.+.beta., 37.degree.+.gamma.) where .alpha.=-5.degree. to +5.degree., .beta.=-5.degree. to +5.degree., and .gamma.=-5.degree. to +5.degree.. The element may be used in a filter that selects the frequency used in a communication device or a resonator that is used in a highly stabilized oscillator.
