MSM6025 Chipset Architecture Featuring QCT's RF CMOS Single-Band Solution
MSM6025 and RF CMOS Single-Band Chipset Solution
radioOne Technology
QUALCOMM's next-generation radio frequency (RF)
As with all members of the MSM6xxx™ family of chipset solutions, the
MSM6025 solution features QUALCOMM's radioOne Zero Intermediate
Frequency (ZIF) architecture, which eliminates the need for intermediate
frequency (IF) components. With radioOne technology, the MSM6025
chipset requires less printed-circuit-board area than previous generations
and reduces time-to-market development and bill-of-materials (BOM) costs.
products are the first CDMA2000® 1X radioOne®
chipsets to use the highly cost-competitive Radio
Frequency Complementary Metal Oxide
Semiconductor (RF CMOS) process technology.
QUALCOMM's cost-competitive single-band solution includes the
MSM6025™ Mobile Station Modem™ (MSM™) chipset, the RF
CMOS RFR6122™ receive radio frequency integrated circuit (RFIC)
and the RFT6122™ transmit RFIC chips, the power management
PM6610™ device, and QUALCOMM's integrated system software —
enabling more cost-effective CDMA2000 1X cellular band voice- and
data-enabled handsets and devices that address the growing need for
reliable, affordable wireless solutions, especially in emerging markets
such as China, India and Latin America.
RFR6122 Device Description
The RFR6122 device is the radioOne Zero
Intermediate Frequency (ZIF) fully integrated receive
RFIC. The device provides an integrated low-noise
amplifier (LNA), a single mixer and baseband filtering
to provide full RF-to-baseband downconversion for
the CDMA cellular band. Included on the chip are an
integrated UHF voltage-controlled oscillator (VCO) and a local oscillator
(LO) generation block, which produce all the LO signals required for
CDMA cellular frequency band of operation. The Rx phase locked loop
(PLL) resides on the RFT6122 companion IC. Extension of standby time is
achieved by selective circuit power-down, gain control and bias current.
These features, along with all of the radioOne chipset functionalities, are
controlled by the QUALCOMM MSM via the serial bus interface (SBI).
Package type is a 32-pin 5 mm x 5 mm Quad Flat No-Lead (QFN32).
CMOS is a low-cost, high-volume digital process technology used for
most of today's digital computer microchips. By migrating RF designs
to a CMOS-based process technology, cell phones and other wireless
handheld devices can leverage significant economies of scale to
provide price-competitive, reliable wireless solutions.
