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.
