Abstract :
With a simple AM-to-PM modeling and system simulation techniques, power amplifier adjacent channel power ratio(ACPR) is calculated for millimeter-wave OFDM wireless LAN. The required amplifier back-off for specified ACPR and the ACPR degradation are predicted for the AM-to-PM nonlinearity. More than 10 dB additional back-off is required if the amplifier has 5° AM-to-PM at the 1.0 dB compression, and the required back-off increases to 1.4 dB as the AM-to-PM increases to 10° compared to the case without phase distortion
