SUMMARY OF BENEFITS
• Ideal for mobile phone integration
• Designed to handle the very harsh environment of mobile
phones while maintaining high radio performance and
optimizing overall phone performance.
• In-band and out-of-band blocking performance significantly
exceeds Bluetooth requirements.
• Fractional-N frequency generation technology eliminates the
need for a dedicated reference crystal, which is an additional
source of RF noise.
• Monolithic implementation in a standard digital
CMOS process with minimal external components
provides a manufacturable low-cost Bluetooth RF/IF
solution.
• On-chip auto-calibration eliminates process variation
across components and mitigates temperature
variation, enabling the chips to be used in high-volume
mobile phone applications.
• The BlueRF RXMODE2 unidirectional baseband
interface supports connection to a wide variety of
baseband devices.
• Applications:
• GSM, CDMA, GPRS, and WCDMA mobile phones
