Abstract :
This paper presents a method to fully automate active load-pull measurements. The main feature of the automation is the use of an electronic vector modulator (EVM). An efficient pseudo-gradient based algorithm is used to control the EVM. This algorithm reaches the desired load in four iterations for most cases. Measurements results of a NE-76184 transistor are also presented
