EDGE/HSPA Multi-Mode, Multi-Band Cellular Transceiver

Highly integrated RF Cellular Transceiver for Multi-mode and Multi-band Applications

The BCM2091 is a highly integrated RF cellular transceiver for multi-mode (EDGE/GPRS/GSM® and WCDMA/HSDPA/HSUPA) and multi-band (850/900/1800/1900/2100 MHz) applications. The device operates in any of the 3GPP bands I-X (with the exception of band VII) and can be configured to interface with single-chain or multi-chain, multi-mode Power Amplifiers (Pas). It supports HSDPA and HSUPA and up to multislot class 3G EGPRS operation.

The BCM2091 RF transceiver provides RF connectivity for Broadcom's BCM21553 HSUPA processor enabling the industry's smallest HSPA transceiver designed in a standard low cost, 65 nanometer CMOS process. It delivers a highly flexible transceiver architecture that provides handset designers with ultimate flexibility in PCB board design and reduces external RF engine component count, which in turn, reduces bill-of-materials (BoM) cost.
