IFT3000
IFR3000 and IFT3000 Devices as Part of QUALCOMM鈥檚 Fifth-Generation Chipset Dual-Mode Cellular (CDMA/AMPS) Handset Architecture
Overview
The QUALCOMM IFR3000鈩?and IFT3000鈩?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 Q5500鈩?Rx and Q5505鈩?Tx AGC
amplifiers. The result is a more economic, two-chip analog baseband
solution which provides handset designers over a 60% reduction
in size.
