BCM2002 Bluetoothtransceiver integrated radio transceiver that optimized 2.4-GHz Bluetooth wireless systems. transceiver Bluetooth compliant designed compatible with Bluetooth-enabled CDMA chipsets. BCM2002 high-performance radio implemented digital CMOS. incorporates fractional-N frequency generation technology synthesize various reference frequencies mobile phone applications. proprietary self-calibrating structure allows both excellent phase noise fast frequency hopping covering entire band. receiver front consists noise amplifier image reject mixer, which provide good performance without costly band pass filter. Balanced mixer structures accurate quadrature signals allow excellent noise figure strong image rejection. frequency allows high performance amplifier filter designs CMOS. bandpass filter structure features selfcalibration circuitry that automatically adjusts circuit elements compensate process variation. This eliminates tuning
ensures that process temperature variation uniform across devices. amplifiers provide limiting function that following stages always constant signal level regardless input level. RSSI signal also generated these amplifiers system determine signal strength. signal then filtered further, demodulated, finally sent slicer generate logic level data output. GFSK transmit signal first generated baseband proprietary modulator. then filtered upconverted using quadrature signals. signal then boosted class Bluetooth output power level power amplifier. Four output power levels digitally programmable from full power power 4-dB steps. BCM2002 controlled baseband interface. This interface provides control various sections chip, defines data transfers, allows access various internal registers device.
