Overview
At QUALCOMM CDMA Technologies (QCT), we strive to constantly
improve the indispensable communication tools we all use every day.
QCT creates state-of-the-art chipsets, system software, development
tools and products such as the LaunchpadTM suite of technologies
and software that support the most advanced digital wireless features
and functionality available for wireless devices and base stations
while continually reducing complexity, cost and board-space
requirements.
3G MSM6050 CDMA Chipset
The MSM6050TM solution, part of QCT's MSM6xxx
Mobile Station Modem (MSMTM) family of chipsets
and system software, uses QCT's revolutionary
radioOneTM Zero Intermediate Frequency (ZIF), or
direct conversion, architecture to support Release
A of the CDMA2000 1X standard, supporting data
rates of up to 153 kbps on the forward and reverse links (FL and RL).
The MSM6050 device, including the radioOne RF components,
reduces the total number of radio components in half, shortens
handset development and test times, simplifies RF calibration, and
enables higher handset production yields. These features contribute to
significantly reducing overall handset design and manufacturing costs
as well as shortening time-to-market.
The MSM6050 CDMA2000 1X solution is optimized to support voice
and key data capabilities while enabling CDMA2000 network benefits.
It provides a seamless migration path from 2G to 3G services and
applications, and the increased voice capacity of a CDMA2000
network. The MSM6050 solution will enable manufacturers to quickly
develop handsets meeting specifications for worldwide cdmaOne and
CDMA2000 1X systems.
The MSM6050 device significantly reduces radio bill-of-materials
(BOM) costs and improves handset standby and talk times over
current solutions. A key enhancement to the MSM6050 chipset over
the previous generation is the integration of QCT's gpsOneTM position
location technology. With the adoption of location-based services and
the FCC E9-1-1 mandate for safety applications, the new generation of
handsets based on the MSM6050 chipset will be able to provide cost-
effective high accuracy position location capabilities.
The MSM6050 chipset solution consists of the MSM6050 baseband
processor, direct conversion RFL6xxx and RFR6xxx receive devices,
the direct conversion RFT6xxx transmit device, PM6xxx power
management device and a compatible power amplifier device. These
devices perform all of the signal processing and power management
in the subscriber unit.
The MSM6050 chipset integrates functions that support tri-mode
CDMA/FM handset operation. Subsystems within the MSM6050
baseband processor device include a CDMA processor, Digital FM
(DFM) processor, QCT's latest generation of DSP, the QDSP4000TM core,
for voice compression and applications support, PLL and an ARM
ARM7TDMI microprocessor. Also integrated in the MSM6050 device are
analog functions such as a wideband mono codec and analog interfaces
for the radioOne RF ASICs. Controllers for a Universal Serial Bus (USB),
device controller for a R-UIM (CDMA SIM), GPIOs, and peripheral
interfaces complete the system integration.
QCT provides a complete software suite, Dual-Mode Subscriber
(DMSS) software, for building handsets around the MSM6050 chipset.
DMSS software is designed to run on a Subscriber Unit Reference
(SURF) phone platform, an optional development platform optimized
to assist in evaluating, testing and debugging DMSS software.
The MSM6050 device is offered in a 208-ball Fine-Pitch Ball Grid
Array (FBGA) production package, which is package compatible with
MSM6000. This package compatibility gives handset manufacturers
the ability to leverage re-use of the radioOne design with a range of
handset models to address different market tiers.
Additionally, the MSM6050 solution supports QUALCOMM's Binary
Run-time Environment for WirelessTM (BREWTM) applications
development platform.
As with all QCT products, the MSM6050 solution features the
unparalleled customer support you have come to expect from your
partner of choice for complete wireless communications solutions. QCT
is committed to providing innovative multi-mode, multi-network
chipsets, system software and development tools that will help ensure
your competitive success in the wireless communications marketplace for
3G and beyond.

gpsOne Technology
QUALCOMM is introducing a new generation of its breakthrough
gpsOne position location technology in the MSM6050 solution. Re-
designed from the original MSM3300 IS-95A/B solution to provide a
more optimized implementation, the gpsOne technology merges Global
Positioning System (GPS) satellite and network information to provide a
high-availability solution with industry-leading accuracy and performance
to a new class of mainstream CDMA2000 1X handsets. This solution not
only meets the FCC E9-1-1 mandate under the most challenging
conditions, but also provides a ubiquitous platform for location-based
applications and services.
The Mobile Station (MS) collects measurements from the GPS
constellation and the cellular/PCS network, then sends the information to
the Position Determination Entity (PDE), which optimizes the position
location calculation based on existing information. gpsOne technology
will enable consumer-priced, position-capable CDMA handsets.
The block diagram illustrates the baseline architecture for the
MSM6050 and CDMA/ GPS terminal devices.
radioOne Technology
The MSM6050 device interfaces directly with QCT's new radioOne RF
ASICs. radioOne is a revolutionary technology for CDMA transceivers
that uses Zero Intermediate Frequency (ZIF), or direct conversion,
architecture for the wireless handset market. This direct conversion
eliminates the need for large IF Surface Acoustic Wave (SAW) filters
and additional IF circuitry, which significantly reduces the handset
BOM, resulting in cost-effective multiband and multimode handsets
that can be produced in smaller form factors.
Using advanced techniques developed by QCT to enable high-
dynamic-range receivers, radioOne solves the problem of stringent
interference specifications with which CDMA phones must comply.
The radioOne technology also incorporates the frequency synthesis
and passive elements used in converting baseband signals to and
from RF. A single external local oscillator is used for the CDMA
receiver, which will provide the capabilities needed to operate on
systems around the world and will simplify the procurement of parts
and the cost of designing CDMA handsets.
