BCM21331

Description

The BCM21331 is a single-chip EDGE/GPRS/GSM multimedia baseband processor with a fully integrated RF transceiver and mixed-signal analog. Based on 65 nm technology, the BCM21331 offers the lowest power consumption, highest integration, and lowest cost EDGE solution. BCM21331 supports Class 33 EDGE/GPRS and integrates all analog and digital baseband functions on a single, monolithic silicon.

The integrated BCM21331 RF transceiver design delivers high RF performance while achieving low-power consumption through innovative architecture and circuit design. The BCM21331 RF transceiver draws on Broadcom's extensive experience in digital CMOS radio design and directly leverages Broadcom's BCM2085 CMOS EDGE radio product. Critical radio performance, while using digital CMOS for radios, is assured through the use of proprietary, autonomous, real-time calibrations within the radio.
