Avago Technologies announced its next-generation quintplexer for mobile handset applications. The company is a leading supplier of analog interface components for communications, industrial and consumer applications. Leveraging the company’s innovative film bulk acoustic resonator (FBAR) technology, the miniature ACFM-7103 quintplexer provides unprecedented PCS insertion loss for best in class power consumption and receiver sensitivity. In addition, this quintplexer can be used in single and dual antenna applications, offering a new level of design flexibility. Avago’s new ACFM-7103 targets CDMA mobile handsets, datacards, and fixed terminal applications, such as femtocells.
Avago’s ACFM-7103 dramatically raises the performance bar for multiplexers. With an improved typical PCS Tx insertion loss of 1.9 dB (3.1 dB max), ACFM-7103 significantly reduces power consumption by 50-70 mA resulting in longer talk time and battery life. A reduction in typical PCS Rx insertion loss to 2.5 dB (3.6 dB max) also increases receiver sensitivity by 1 dB over previous generations. Additionally, a 1.0 dB typical (1.7 dB max) GPS insertion loss results in excellent receiver sensitivity for wireless devices in the GPS chain.
The ACFM-7103 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 miniature 4.0 x 7.0 x 1.2 mm package. Compared to discrete solutions, ACFM-7103 reduces PCB space by over 50% and provides better performance due to its highly integrated architecture. The pin-out of the ACFM-7103 is ideally matched to the latest Qualcomm QSC CDMA chipsets resulting in the shortest design time and minimized line routing. Unique, dual antenna support in the ACFM-7103 enables multi-function mobile devices to provide better performance for applications such as GPS, where a dedicated antenna is desired.
