Qualcomm has announced the availability of its radioOne Zero IF (ZIF) CDMA single-band chipset, consisting of the RFT6120 baseband-to-RF transmit processor and the RFR6120 or RFR6125 RF-to-baseband receive processors. The RFR6125 features the company's gpsOne position location capability.

The two-chip solution performs the radio functions that formerly required three ICs. In addition, the ICs are offered in smaller packages and include integrated LNAs and UHF VCOs. The radioOne architecture also eliminates the need for IF components, including IF ICs, IF SAW filters, IF VCOs.

"Qualcomm's second-generation ZIF architecture integrates all of the active circuitry needed for CDMA receive and transmit functionality except for the power amplifier," said Don Schrock, president of QUALCOMM CDMA Technologies. "These new chips offer the highest integration and lowest cost solutions for single-band cellular CDMA applications on the market."

The RFR6120 and RFR6125 chips are offered in a 6-by-6mm 40-pin QFN package, while the RFT6120 is available in a 5-by-5mm 32-pin QFN
