The RF110 is a three-stage class AB power amplifier for 2400–2483.5 MHz ISM (Industrial, Scientific, Medical) band applications.
The RF110 power amplifier, combined with Conexant's RF109 transceiver, forms a complete system solution for a direct conversion 2400 MHz radio which is compliant with FCC Part 15 regulations in the ISM band.
The RF110 is operational in the 2400 MHz ISM band with a supply voltage range of 3.0–4.5V. The RF110’s pin assignments and block diagram are shown in Figure 1 and Figure 2, respectively.
