RF Power Amplifiers and AM – AM and AM – PM conversion

Following on to the recent post on power amplifier specifications http://www.signalpro.biz/wordpress/?s=rf+power+amplifier+specifications&submit=Search  another important dual set of specifications is the AM_AM and AM РPM specifications of the power amplifier. These are important for amplifiers that must be used to transmit data constellations which need both AM accuracy and stability and PM accuracy and stability. The result of not taking these into account ( in these types of applications) would result in severe errors in reception of the data ( EVM problems) thereby leading to increased BER ( which is another way of stating the result). Please check on this blog later for a more detailed look at these impairments.
