QUALCOMM announces the RFR6155™ device, a 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. Both chips are a 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 RFR6155 device is a 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. The RFT6150 device is offered in a 5 × 5 mm, 32QFN package and will sample in Q4 2004. The RFR6155 device, which will sample in Q2 2005, is offered in a 6 × 6 mm, 40-pin Quad Flat No-Lead (40QFN) package.
