BQB qualified Bluetooth V1.1 radio transceiver
Fractional-N frequency generation
• Supports 12, 13, 19.2, 19.68, or 19.8 MHz reference
frequencies
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.
Differential RF interface
•
• Fractional-N frequency generation technology eliminates the
need for a dedicated reference crystal, which is an additional
source of RF noise.
Typical -80 dBm receiver sensitivity under high
•
interference environments
Typical +3 dBm RF output power satisfied
requirements for Class 2 operation
Strong spurious emissions performance
• Minimal filtering required to meet mobile phone integration
requirements
Excellent blocking performance
• Minimal filtering required to meet mobile phone integration
requirements
Highly linear receiver exceeds Bluetooth specifications
•
•
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.
•
•
Meets FCC radiated emissions requirements without
•
RF filtering or shielding
Low power consumption
Built-in digital RSSI
Programmable PA gain
8mm x 8mm, 52-pin LPCC standard package
Applications:
•
•
•
•
• GSM, CDMA, GPRS, and WCDMA mobile phones
