The LX5531 is a power amplifier optimized for 802.11ac/a/n applications in the 5.15-5.85GHz frequency range. The LX5531 includes a three-stage PA, active bias, input/output matching, and a harmonic filter. The power amplifier operates with a single positive voltage supply of 5V, and provides power gain of 32dB and output powers of 23 and 25dBm at 5V across the frequency band for -35 and -30dB dynamic EVM (DEVM), respectively. It is fully matched to 50 Ohms on both the input and output ports.
