IFR3500 Functional Block Diagram

Overview

The range of supply voltage is from 2.7 V to 3.0 V,

which provides operating compatibility for platforms

utilizing a single-cell Li-Ion battery design. CDMA

and GPS mode selection, gain control, IF LO

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 Launchpad™ 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.

frequency divide, and selective power-down modes

which permit optimized power savings are controlled

directly from the MSM device and system software. The IFR3500 device

is provided in a 32-pad BCC++ plastic package that includes an

exposed center ground slug for improved RF grounding, mechanical

strength, and thermal continuity.

The IFR3500™ device is a fully integrated IF-to-baseband processor

performing all CDMA and GPS receive (Rx) signal processing functions

required between the IF output from QCT’s RFR3100™ or RFR3300™

Rx front-end devices and at baseband with Mobile Station Modem

(MSM™) devices for IS-95 CDMA-only and ARIB-53 (Japan) J-CDMA

applications. The IFR3500 device leverages previous IFR3300™ circuit

designs, including GPS, and provides significant advantages in size and

cost for single-mode CDMA or single-mode plus gpsOne™- enabled

handsets. In conjunction with RFR3100 or RFR3300 devices, a

complete two-chip Rx radio implementation for CDMA handsets with

GPS position location capability is realized with minimum circuitry.

As with all QCT products, the IFR3500 device 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 wire-less communications marketplace for 3G and beyond.

Features

• Dual-mode operation includes CDMA and GPS

• Rx digital baseband interface compatible with MSM3100™,

MSM3300™, MSM5105™, MSM5100™, and MSM5500™ devices

• IF LO synthesizer can be shared between IFR3500 and RFT3500

devices for easier frequency planning and reduced cost

• Rx power control through 90 dB dynamic range VGA

• IF mixer for down-converting IF to analog baseband for CDMA and

GPS

The IFR3500 device includes IF AGC amplifiers, IF VCO, selectable

frequency divider for IF LO, a quadrature IF-to-baseband downconverter,

in-phase (I) and quadrature (Q) baseband filters, and Analog-to-Digital

Converters (ADCs). Used in conjunction with QCT’s RFT3500™ device,

the IFR3500 device accommodates sharing of the IF LO synthesizer to

enable simplified frequency plans and reduced cost.
