Abstract(in English) | We are investigating load pull system required for efficient design of load circuit and matching circuit which can improve efficiency of microwave amplifier. Among them, we reported on active load-pull system (ALP) which is superior to the conventional method in measuring speed, accuracy, impedance tuning range, measuring instrument size. However, although the general open-loop and closed-loop ALP systems that have been examined have merits in their respective methods, it is a problem that there are problems with the ease of control of the reflection coefficient and phase angle, the tuning range, and the stability of the system I understood. Therefore, in this paper, based on simulation and experimental results, we will describe the causes of those problems and propose solutions. |
