Hi Adrian, We are using AR9390 as our radio chip-set. We did some experimentation for both 2.4 and 5GHz Transmitter Tx balun output. And we found EVM for 2.4 GHz -25 dB and for 5GHz -17dB, while setting Tx set power is 25dBm. As per IEEE std's EVM specification for 2.4/5Ghz is -30dB.
So is there any way to improve this EVM values from -17 to -30dB for 5GHz? Also please note that, I checked EVM values before and after Power Amplifier, EVM value is same.
