A novel multiharmonic load-pull system based on an active load tuning configuration is presented. The system allows independent load-tuning of an excitation signal and its harmonics. Load-pull measurements on a MESFET (NEC 71083) have been performed at the fundamental (f/sub 0/), second (2f/sub 0/), and third (3f/sub 0/) harmonics. The results show the importance of such measurements in designing and modeling nonlinear devices and circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
