Quintplexer offers antenna apps low power use

Avago Technologies Inc. launched its next-generation quintplexer for mobile handset applications. Leveraging the company's film bulk acoustic resonator (FBAR) technology, the miniature ACFM-7103 quintplexer is believed to provide unprecedented PCS insertion loss for best-in-class power consumption and receiver sensitivity. Targeting CDMA mobile handsets, datacards, and fixed terminal applications such as femtocells, this quintplexer can be used in single and dual antenna applications.

This quintplexer integrates two duplexers, one filter, one triplexer and several other components, depending on the RF application. Thirty percent smaller than its predecessor, the ACFM-7103 is housed in a 4.0mm x 7.0mm x 1.2mm package.

With an improved typical PCS Tx insertion loss of 1.9dB (3.1dB max), the ACFM-7103 significantly reduces power consumption by 50mA to 70mA, resulting in longer talk time and battery life. A reduction in typical PCS Rx insertion loss to 2.5dB (3.6dB max) also increases receiver sensitivity by 1dB over previous generations. "A 1.0dB typical (1.7dB max) GPS insertion loss results in excellent receiver sensitivity for wireless devices in the GPS chain," Avago said.

The ACFM-7103 is currently showcased at the 2008 MTT-S International Microwave Symposium in Atlanta, Georgia.
