Description

The BCM2004 all-CMOS radio delivers significant size, cost and performance advantages over existing Bluetooth radio solutions while providing the highest level of chip integration, eliminating all active external components. Leading the industry in radio sensitivity and transmit power, the new radio BCM2004 enables the lowest added bill-of-materials cost for integration of high-performance Bluetooth radios into QUALCOMM chipset-based 3G CDMA mobile handsets.

The BCM2004 provides strong spurious and blocking performance that supports simultaneous operation with GPS, CDMA, WCDMA, and GSM/GPRS worldwide radio frequency plans. On-chip auto calibration eliminates process variation across components and mitigates temperature variation, BCM2004 enabling consistent performance in high-volume applications. In addition, the exceptional blocking performance capability of the BCM2004 exceeds Bluetooth requirements, eliminating RF filtering to receive strong, reliable signals from other Bluetooth devices. The fractional-N frequency generation technology feature eliminates the need for a dedicated reference crystal. The BCM2004 Bluetooth radio is the next-generation of the BCM2002, which is currently the industry's most widely used radio based on QUALCOMM's proprietary specification for Bluetooth enabled handsets.
