Qualcomm Announces Single-Chip, RF Transceiver with Integrated GPS

Feb 13, 2006 gps navigation, misc news

Qualcomm today announced the industry’s first single-chip UMTS radio frequency (RF) complementary metal oxide semiconductor (CMOS) transceiver with receive diversity and GPS. The RTR6285™ is the world’s most advanced multi-mode UMTS/EGPRS transceiver with integrated receive diversity and GPS, providing global roaming with multi-band UMTS and quad-band EGPRS. Integrated receive diversity on the RTR6285 transceiver enables increases in network capacity of up to 50 percent and of up to 100 percent for average HSDPA data throughput. The integration of GPS functionality helps meet demand for location and emergency services, while minimizing the cost of offering GPS by eliminating the need for many additional components.

“The RTR6285 transceiver’s architecture provides the highest level of RF integration in the industry to achieve the smallest footprint for a multi-band, multi-mode transceiver,” said Dr. Sanjay K. Jha, president of QUALCOMM CDMA Technologies. “This will enable device manufacturers to cost-effectively develop global handsets with small and slim form-factors, while enabling increased capacity and throughput for network operators with integrated receive diversity.”

The RTR6285 transceiver supports the following bands:

* North American triple-band UMTS (bands 2, 4, 5)
* Japanese triple-band UMTS (bands 1, 6, 9)
* European, Chinese and rest-of-world triple-band UMTS ( bands 1, 3, 8 )
* Global quadruple-band GSM and EDGE (800/900/1800/1900 MHz)… read
