San Diego, Calif.—Quorum Systems Inc. has introduced an ultra-low-power, multi-band, multi-mode RF transceiver, the Sereno QS3200, adding TD-SCDMA support to its existing 2G/2.5G/3G RF transceiver family.

Quorum's QS3200 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 digital transmit architecture removes the need for external transmit SAWs for TD-SCDMA as well as GPRS/EDGE.

Compared with conventional devices, the QS3200 eliminates four chips from the radio BOM, without the need for costly modules, according to the company. The integration of LNAs and removal of transmit SAWs and Baluns further reduces the resulting radio footprint and cost.
