- Fully integrated receiver with high sensitivity
- Integrated low phase noise VCO
- Dedicated Bluetooth Phase-Locked Loop (PLL) synthesizer
- 4 d Bm 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 Bi CMOS device is a low power, highly integrated circuit. It features a fully integrated receiver, from antenna filter output to the demodulated data output,
UAA3558 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...
