The LX5535 is a power amplifier optimized for WLAN applications in the 2.4-2.5 GHz frequency range. The PA is implemented as a three-stage monolithic microwave integrated circuit (MMIC) with active bias and output pre-matching. With single low voltage supply of 5V, it provides 32 dB power gain between 2.4-2.5GHz, at a low quiescent current of 120mA. The output power for EVM(Error Vector Magnitude) of 3.5% is 25dBm (64QAM/54Mbps), where the PA consumes 260mA total DC current.
