Overview

The QUALCOMM IFR3000TM and IFT3000TM Rx and Tx IF/Baseband

processors offer significant reduction in cost, size and pin count over

previous generation products. By integrating the functionality of three

Application Specific Integrated Circuits (ASICs) into two ASICs,

designers now possess IF-to-Baseband and Baseband-to-IF processing

power, and Rx and Tx Automatic Gain Control (AGC) circuitry on either

two 48-pin Low-profile Quad Flat Pack (LQFP) packages or two 48-pin

Bump Chip Carrier (BCC) packages.

The IFR3000 and IFT3000 Rx and Tx IF/Baseband processors are

designed for use in dual-mode CDMA and FM portable cellular

telephones. The IFR3000 and IFT3000 devices interface between the

radio-frequency (RF) section and the digital processing circuitry of the

telephone.

Smaller Packaging

The IFR3000 and IFT3000 devices incorporate all the Rx and Tx

processing capability of the QUALCOMM Q5312 Analog Baseband

Processor (BBA2-shrink) together with the automatic gain control

functionality of the QUALCOMM Q5500TM Rx and Q5505TM Tx AGC

amplifiers. The result is a more economic, two-chip analog baseband

solution which provides handset designers over a 60% reduction

in size.
