摘要： A surface acoustic wave device including a piezoelectric substrate having NSPUDT behavior and a directionality reversed electrode structure including positive electrode, negative electrode and floating electrode. Positive and negative electrode fingers each having a width of .lambda./8 are arranged interdigitally at a pitch of .lambda. and floating electrode fingers having a width of 3 .lambda./8 are arranged between successive positive and negative fingers with an edge distance of .lambda./8. A directivity due to NSPUDT behavior of the substrate can be reversed. Positive and negative electrode fingers are arranged interdigitally at a pitch of .lambda. and between successive positive and negative electrode fingers are arranged floating electrode fingers having a reflecting coefficient different from that of the positive and negative electrodes.

摘要： A surface acoustic wave device including a substrate made of a lithium tetraborate single crystal (Li.sub.2 B.sub.4 O.sub.7) whose cut and propagating direction are determined such that Euler cut angles (.psi., .theta., .phi.) are .psi.=+5.degree..about.-5.degree., .theta.=9.degree..about.29.degree. and 32.degree..about.86.degree. and .phi.=85.degree..about.95.degree., and an electrode structure formed on a surface of the substrate to realize a natural single-phase unidirectional transducer property together with an anisotropy of said substrate. A lithium tetraborate substrate having cut angles of (0.degree., 51.degree., 90.degree.) shows an ideal NSPUDT and a lithium tetraborate substrate having cut angles of (0.degree., 78.degree., 90.degree.) reveals a zero temperature coefficient of delay. A directionality reversed electrode structure or a directionality corrected electrode structure may be advantageously used.
