Qualcomm adds RF CMOS product to support dual-band CDMA2000 1X

May 13, 2004

Qualcomm announced the RFR6155 device, the Company's first dual-band RF CMOS (Complementary Metal Oxide Semiconductor) receive chip for CDMA2000 1X, and the RFT6150 transmit device for dual-band roaming capabilities. The RFR6155 device also integrates a GPS receiver, which supports Qualcomm's gpsOne solution, the world's most broadly deployed assisted-GPS handset technology. The RFR6155 and RFT6150 chips are a cost-effective radioOne Zero Intermediate Frequency (ZIF) solution supporting both low-band Japan CDMA/Cellular (800 MHz), and high-band Korean PCS (1800 MHz)/PCS (1900 MHz) and IMT (2100 MHz) frequency. The enhanced integration of the RFR6155/RFT6150 solution simplifies radio design and promotes cost reduction to enable affordable wireless devices for expanding CDMA2000 markets, including China, Japan, Korea, Latin America and North America.

The RFR6155 device is a cost-optimized radioOne receiver providing full RF-to-baseband down conversion, including integrated low-noise amplifiers (LNA), a voltage controlled oscillator (VCO), local oscillator (LO) generation, phase locked loop (PLL), direct down conversion mixers and integrated baseband filters - resulting in reduced system power consumption. The RFT6150 chip is a radioOne dual-band transmit chip providing full baseband-to-RF up conversion with an optimized footprint for further space-saving advantages.

The RFR6155 and RFT6150 chips are a dedicated dual-band CDMA2000 1X RF solution that reduces board area by optimizing package size. The RFT6150 device is offered in a 5mm x 5mm, 32QFN package and will sample in Q4 2004. The RFR6155 device, which will sample in Q2 2005, is offered in a 6mm x 6mm, 40-pin Quad Flat No-Lead (40QFN) package. Qualcomm also announced the on-time sampling of the wireless industry's first single-band CDMA2000 1X RF CMOS solution.
