Bluetooth RF Transceiver
FEATURES Low cost solution for a Bluetooth radio Fully integrated receiver with high sensitivity Integrated low phase noise VCO Dedicated Bluetooth Phase-Locked Loop (PLL) synthesizer 4 dBm programmable transmitter preamplifier with an integrated switch 3-line serial interface bus Low current consumption from 3.0 V supply. APPLICATIONS 2400 to 2497 MHz Bluetooth radio transmission and reception in the Industrial Scientific and Medical (ISM) band. GENERAL DESCRIPTION The UAA3558 BiCMOS device is a low power, highly integrated circuit. It features a fully integrated receiver, from antenna filter output to the demodulated data output,

an integrated VCO, a synthesizer to implement Bluetooth channel frequencies, and a transmitter preamplifier to drive either the switch diode to antenna or a power amplifier. The synthesizer’s main divider is driven by the prescaler output in the range of 2400 to 2497 MHz and programmed via a 3-wire serial bus. The reference divider ratio can be programmed to 12, 13, 16 or 26. Outputs of the main and reference dividers drive a phase comparator, where a charge pump produces phase error current pulses for integration in an external loop filter. The charge-pump current (phase comparator gain) is set to 3.5 mA. The synthes...
