Overview

? Bluetooth Transveiver for the 2.4 GHz ISM Band

(RF range 2378-2497 MHz)

? Part of complete Infineon Bluetooth

chipset solution

? Completely integrated receiver with outstanding

RF performance:

best in class sensitivity and blocking

? Low current consumption

? No external IF filters or RF filters necessary

? B6HFC BiCMOS technology, 25 GHz ft

? fully balanced self adjusting VCO with integrated

varactor diodes for receive and transmit mode

? Prescaler and PLL on-chip with 1 MHz charge pump reference frequency

? Supply voltage regulators for the VCO and the analogue part

? Internal current reference for PLL charge pump to get constant lock-in time
