Avago Technologies unveils a new quintplexer module delivering high GPS performance levels. 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 optimize performance, the ACFM-7102, which is based on film bulk acoustic resonator, provides designers with flexibility and simplicity when creating ultrasmall, high-performance cellphones that deliver simultaneous GPS functionality.

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 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.

Utilizing 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 -30C to 85C 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 $4 in small quantities. General availability is scheduled for Q3 '07.
