APPLICATIONS 2402 to 2480 MHz Bluetooth radio transmission and reception in the Industrial Scientific and Medical (ISM) band conforming to the “Bluetooth Specification Version 1.1.” GENERAL DESCRIPTION The UAA3559HN BiCMOS device is a low-power, highly integrated circuit. It features a fully integrated receiver for demodulating the output signal from an external antenna filter, an integrated VCO, a synthesizer to implement Bluetooth channel frequencies, and a transmitter preamplifier. The output power of the transmitter preamplifier can be programmed in eight steps from −7.5 dBm to +9 dBm (typical) and drives either an antenna via an external switch diode or an external power amplifier.
