A small surface acoustic wave (SAW) duplexer for a wide-band code-division multiple access (W-CDMA) system with a good temperature coefficient of frequency (TCF) has been required. However, the conventional SAW duplexer for W-CDMA using Al electrode/

Currently, miniature surface acoustic wave (SAW) devices (filters and duplexers) with a good temperature stability are strongly required. In order to realize its requirement, various SAW substrates combining a high density metal electrode, a SiO 2 fi

A surface acoustic wave demultiplexer includes a first surface acoustic wave filter, a second surface acoustic wave filter having a higher center frequency than the first surface acoustic wave filter, and a one-port surface acoustic wave resonator co
