Quorum Intros Transceiver Chip

SAN DIEGO -- Quorum Systems, Inc. introduces its latest high performance, ultra-low-power, multi-band, multi-mode radio frequency (RF) transceiver, the Sereno(TM) QS3200, adding TD-SCDMA support to the company's already existing 2G/2.5G/3G RF transceiver family. Built on a single-die, the QS3200 represents the world's highest integration TD-SCDMA+ GSM/GPRS/EDGE transceiver announced to date, offering dramatic + reductionsin radio area and bill of materials (BOM) for mobile phone designers. The company is currently working with baseband partners and expects platform reference designs utilizing the QS3200 to be available in mid-2008.

Quorum's QS3200 true single-chip multi-mode transceiver, implemented in bulk CMOS, simultaneously supports dual-band (1900MHz and 2000MHz) TD- SCDMA/HSPDA Category 10 and Quad-band (USGSM850, GSM900, DCS1800, PCS1900) GSM/GPRS/EDGE. Derived from Quorum's existing, QS3000 WCDMA+EDGE transceiver, the QS3200 also integrates all six LNAs, requires no external Baluns, and its unique digital transmit architecture removes the need for external transmit SAWs for TD-SCDMA as well as GPRS/EDGE. Compared with solutions in the market today, it removes as many as four chips from the radio BOM, without the need for costly modules. The integration of LNAs and removal or transmit SAWs and Baluns further reduces the resulting radio footprint and cost.

By leveraging Quorum's proven 2.5G architecture utilized today in the QS500(GSM/GPRS) and QS1000 (GSM/GPRS/EDGE) transceivers, in addition to size and cost reductions, the QS3200 also offers world-class radio performance and best-in-class receiver power consumption, helping designers achieve best-in- class handset standby and talk times.

"Using the same, proven core architecture on all our designs has allowed us to deliver quality products across the standards associated with mobile communication," stated Dr Bernard Xavier, Quorum Systems' president and CEO."Having gained years of experience at designing 2.5G and 3G transceivers in bulk CMOS, our company is also very well positioned to support the increasing demand for cost competitive, high performance, solution-on-chips that incorporate baseband and radio on a single die."
