Passive Load-Pull Systems

  • Fadhel M. Ghannouchi
  • Mohammad S. Hashmi
Part of the Springer Series in Advanced Microelectronics book series (MICROELECTR., volume 32)


Chapter 2 provides details of passive load-pull systems and impedance tuning and synthesis approaches. Primarily two types of passive tuners—the electromechanical tuner (EMT) and the electronic tuner (ETS)—are employed in load-pull systems. This chapter presents a thorough discussion on the theory and concepts of both these tuners and provides in-depth knowledge on these tuners, so that the readers can select the best cost-effective solutions for their fundamental and harmonic load-pull applications. In the second part of this chapter, calibration techniques to remove errors arising from mismatches, dispersions and imperfections in the cables and system components are provided, as well as the required algorithms of calibration.
