Abstract :
RF power amplifier efficiency and power output can be measured accurately without an RF power meter. The authors transfer to DC the measurement of RF voltage across a calibrated RF load which can be nominal resistive or nonnominal with parallel susceptance. They give an analysis of accuracy, including effects of RF harmonics.
