ABSTRACT: The authors introduce the concept of active load pull, discuss the challenges related to performing gain compression power sweep and active load pull measurements on high-power devices at sub-THz frequencies, and then demonstrate a novel solution using high-power waveguide extender modules to overcome these challenges, compress the device under test, and extend load pull iso-contours to higher magnitudes of reflection.
