Surface acoustic wave device

摘要

The surface acoustic wave device (1) includes a quartz rotated Y-cut plate (2) and at least one interdigital transducer (5) disposed on the quartz rotated Y-cut plate. The quartz rotated Y-cut plate has a Euler angle represented by (0, THETA , phi ). The angle THETA is within a range of about 125 DEG < THETA <130 DEG or equivalents thereto, and the angle phi is approximately 90 degrees. The interdigital transducer is made e.g. of tungsten or tantalum. <IMAGE>
