Texas Instruments is sampling what it claims is the industry’s first single-chip, dual-band WCDMA RF transceiver for advanced 3G mobile devices.
The TRF6302 combines functions of TI’s TRF4150 single-chip WCDMA transmitter and TRF5150 single-chip WCDMA receiver, which are already in production and shipping in handsets today.
The TRF6302 consumes less than 30mA of current for receive (RX) and less than 60mA for transmit (TX) while supporting a 6dBm output power level. This combination offers a 20% power reduction over existing RF solutions and is the industry’s lowest for such a device.
The TRF6302 supports both 800 MHz and 2100 MHz band operations and offers reduced complexity and requires fewer external filters over devices based on intermediate frequency (IF) techniques. The device features TI’s advanced direct conversion (DC) technology that provides integration of numerous functions, including voltage control oscillators (VCOs), low-noise amplifiers (LNAs), phase lock loops (PLLs), loop filters, synthesisers and low dropout regulators (LDOs).
The TRF6302 is a key component of TI’s TCS4105 four-chip UMTS solution for handsets, smartphones, wireless PDAs, PC cards and other devices.
Along with the TRF6302 dual-band WCDMA RF transceiver, other components of the TCS4105 chipset include the TBB4105 UMTS digital baseband, the TWL3024 analog baseband and power management device, and the TRF6151 quad-band GSM/GPRS single-chip transceiver which is already in high-volume production.
The TCS4105 chipset can be coupled with a TI OMAP applications processor to support 3G multimedia applications such as imaging and video, video conferencing, interactive 3D gaming, location-based services and others.
Samples of the TRF6302 are available today with full production planned for the second quarter of 2004.
