RF106

RF106 900 MHz Power Amplifier Product Description The RF106 is a class AB RF power amplifier for 900 MHz ISM band applications. It delivers output power proportional to the input signal power. The RF106 power amplifier, combined with Conexant's RF105 diSSTance™ (digital Spread Spectrum Technology) transceiver, forms a complete system solution for a direct conversion 900 MHz diSSTance radio which is fully compliant with FCC Part 15 regulations in the ISM band. The RF106 is operational in the 900 MHz ISM band with supply voltage ranging from 2.7V to 5V. It is available in a small 20-pin TSSOP package, shown in Figure 1. Figure 2 shows a block diagram for the RF106.
