An experimental study of switching GaN FETs in a coaxial transmission line

Abstract

Abstract: The switching characteristics of GaN FETs have not yet been measured accurately because of their small electromagnetic size in relation to the circuit and the electromagnetic environment the measurements are exposed to. Switching GaN FETs in a transmission line will allow for measurements to be taken in an electromagnetically defined environment. The transmission line is adapted to take optimum measurements. This is proven by the waveforms presented
