Abstract
True RMS power demodulation system and method for a modulated RF signal uses a DC coupled linear amplifier and linearizes the diode detector prior to demodulation. The demodulated signal is proportional to the difference of RF powers such that the network measurement is unaffected by the modulation depth at the power sensor which can be degraded by RF feedthrough or the presence of an interfering signal or noise.
