Qualcomm Announces RTR6250 UMTS/GSM RF Chip to Enable Worldwide
Roaming for UMTS Terminals
December 17, 2002
Qualcomm today announced the radioOne RTR6250 chip, a fully integrated
transceiver/transmitter for UMTS (WCDMA) and GSM systems. The RTR6250
device, which features radioOne Zero Intermediate Frequency (Zero
IF) architecture, interfaces directly with Qualcomm's MSM6250 Mobile
Station Modem (MSM) baseband processor and supports dual-mode, quad-band
GSM transceiver operations [GSM 900, Digital Cellular System (DCS)
1800, and GSM 850 and 1900] and UMTS transmit operations for 1900
MHz and 2100 MHz.
"By adding GSM 850 and 1900 MHz capabilities to the RTR6200 chip,
the RTR6250 chip will help enable worldwide UMTS and GSM roaming,"
said Don Schrock, president of Qualcomm CDMA Technologies. "This
increases the already high level of integration that the RTR6200
device enabled, and will enhance the cost-effective 3G solution
that Qualcomm offers to manufacturers of handsets for the UMTS and
GSM marketplace."
Qualcomm's radioOne ZIF architecture eliminates the need for IF
components - including IF chipsets, IF Surface Acoustic Wave (SAW)
filters and IF voltage controlled oscillators (VCOs) - thereby reducing
printed-circuit-board area and bill-of-material costs for future
wireless handsets and other devices, enabling more cost-effective
multimode, multiband phones.
The MSM6250 chipset solution supports data rates of up to 384 kbps
and is compatible with the advanced feature set of Qualcomm's Launchpad
suite of technologies, including MPEG-4 video encoding/decoding,
fast JPEG encoding/decoding, MP3 audio decoding, a 2D/3D graphics
accelerator for advanced gaming applications, a MIDI synthesizer
and a megapixel digital camera interface.
