  • Surface acoustic wave device having gap between surface acoustic wave filters covered by sealer
    Patent number: 7781936
    Abstract: A surface acoustic wave device includes a base substrate, first and second surface acoustic wave filters mounted on a surface of the base substrate, and a sealer provided on the surface of the base substrate and covering the first and second surface acoustic wave filters. The first and second surface acoustic wave filters include first and second piezoelectric substrates. The second piezoelectric substrate is located away from the first piezoelectric substrate via a gap. This surface acoustic wave device reduces inter-modulation.
    Type: Grant
