摘要： A piezoelectric wafer of single crystal berlinite, having a surface defined by an X-axis boule cut at an angle in the range from about.94-104, provides an improved substrate for a surface acoustic wave device. These cut angles are relatively easy to fabricate, provide excellent temperature compensation in a range from -55°C to 125°C, and have high piezoelectric coupling coefficient.
