Avago Technologies has unveiled a new quintplexer module based on film bulk acoustic resonator that provides designers with flexibility and simplicity when creating small, high-performance cell phones that deliver simultaneous GPS functionality. The highly integrated and compact ACFM-7102 quintplexer delivers a significant improvement in insertion loss while delivering high GPS to cell band, and GPS to PCS band isolation. With a switchless design to optimise performance, the ACFM-7102 delivers high GPS performance levels.

A 1.9dB insertion loss in its GPS filter path gives the ACFM-7102 high performance levels for concurrent GPS operation. ACFM-7102 also delivers excellent GPS to cell transmitter and GPS to PCS transmitter isolation enabling single antenna simultaneous GPS operation and delivering excellent GPS sensitivity. By fully integrating the GPS filter with cell and PCS duplexer into one small module, ACFM-7102 enables the development of single antenna dual-band, simultaneous GPS handsets that are thinner, with longer overall battery life and improved performance. Avago's ACFM-7102 is also suitable for small PC cards, PDAs and other dual-band wireless devices.

Utilising Avago's FBAR filter process and innovative Microcap bonded-wafer chip scale packaging technology, ACFM-7102 is available in a small 5-by-8-by-1.2mm thick module. Avago's quintplexer module operates in -30?C to 85?C and is compatible with CDMA and W-CDMA third 3G technology that supports voice, data, images and video communications at speeds up to 2Mbps.

ACFM-7102 is currently in limited release. Pricing starts at under Rs.169.08 ($4) in small quantities. General availability is scheduled for Q3 '07.
