Accurate measurement of RF power amplifier efficiency and power output without an RF power meter

Nathan O. Sokal, Alan D. Sokal

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.
