A description is given of a low-loss, high-power surface acoustic wave (SAW) filter developed for an antenna duplexer used in an 800-MHz portable telephone transceiver. The ladder-type configuration uses SAW resonators and capacitors between electrode fingers and ground. The device is fabricated on a 20-mm-square LiTaO/sub 3/ chip. This configuration provides insertion loss as low as 1.0-1.2 dB and output power up to 2 W at 800 MHz. Experimental results from a miniature antenna duplexer-module using this SAW filter as a transmitter filter and previously published high-performance SAW filters as receiver filters are also presented and compared.>
