In this article, a drain‐source voltage and current waveforms measurement method for a fabricated power amplifier is presented. Harmonic components of the drain‐source voltage and the current were obtained using measured output voltage and harmonic ABCD matrices of a load matching network. The drain‐source voltage and current waveforms of a fabricated power amplifier that is operated nonlinearly were successively measured using the proposed measurement method without any influence in the power amplifier operation. © 2012 Wiley Periodicals, Inc.
