SURFACE ACOUSTIC WAVE DEVICE, SURFACE ACOUSTIC WAVE OSCILLATOR, AND ELECTRONIC APPARATUS |
| 摘要 |
A surface acoustic wave device includes: a quartz substrate with Euler angles of (&phgr;, &thetas;, ψ); and an IDT which excites a surface acoustic wave in an upper mode of a stop band; wherein, the Euler angle &phgr; is −60°≦̸&phgr;≦̸60°, and the Euler angle &phgr; determines the ranges of the Euler angles &thetas; and ψ. |
