RF5163
Figure 1 below shows the major component line-up for an ultra linear fixed application (e.g., an access point (AP)) transmitter
capable of producing +26dBm RF P_OUT with an amplifier stage (driver + final stage power amplifier IC, RF2373 + RF5163) EVM
contribution of < 2.5% EVM, RMS (mean).

The RF5163PCBA-WD Evaluation Board employs the RF2373 as a driver amplifier at the input to the RF5163 (as final stage
power amplifier IC). The RF2373 is a very high linearity single stage low noise amplifier (LNA)/driver amplifier that demon-
strates approximately 15dB of gain from 2400MHz to 2500MHz and is capable of delivering +6dBm RF P_OUT at < 1% EVM
(RMS, mean). The RF5163PCBA-WD Evaluation Board is designed to maximize both useful gain and ultra linear transmit power
performance. Typical RF5163PCBA-WD Evaluation Board specifications are shown in the Table below:
