Description
The IFT3000-TQFP-TR is an electronic component model that falls under the category of IC Chips. It is part of the QUALCOMM IFR3000™ and IFT3000™ series of Rx and Tx IF/Baseband processors. These processors provide a significant reduction in cost, size, and pin count compared to previous generation products. They integrate the functionality of three Application Specific Integrated Circuits (ASICs) into two ASICs, offering IF-to-Baseband and Baseband-to-IF processing power, as well as Rx and Tx Automatic Gain Control (AGC) circuitry. The IFT3000-TQFP-TR is designed for use in dual-mode CDMA and FM portable cellular telephones, acting as an interface between the RF section and the digital processing circuitry of the telephone.
