Abstract
A method for measuring the forward power output of an amplifier with improved accuracy with a mismatched load based on probing the amplitude of the AC voltage and current in the final amplifier stage. Amplitudes are combined resulting in a composite reading that is affected less by load mismatch. Variations include measuring signal amplitude at two points 90 degrees apart in the transmission medium and measuring the power supply voltage and current of a saturated amplifier.
