MSM6025 and RF CMOS Single-Band Chipset Solution

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.

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.

radioOne Technology

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.

RFR6122 Device Description

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).
