Miniaturized SAW Duplexer

Mon, 10/03/2005 - 9:16am

Murata Electronics North America introduces an ultra-small SAW duplexer series appropriate for wireless communication products using CDMA800 technology such as cell phones and laptop computers. The advanced SAW duplexer series (global part number SAYSW836MAF0F00), features decreased footprint, higher isolation and attenuation, low insertion loss, better reliability and increased power handling. By upgrading the mounting method of the piezoelectric element from wire bonding to flip-chip construction, the SAW duplexer’s footprint was reduced 52% when compared to its predecessors. This new duplexer measures 3.0 mm × 2.5 mm × 0.80 mm. In spite of the reduced footprint, the SAW Duplexer achieves higher isolation characteristics through the optimization of the piezoelectric element materials and the electrode design. The devices offer a warranted product life of 50,000 hours under an ambient temperature of 50° C at 1.0 W.
