Application Card Overview

As designs move into higher frequency bands with ever-tighter accuracy margins, power measurement can no longer be an afterthought. Achieving reliable results means measuring directly on the device under test inside a thermal vacuum chamber—where losses, reflections, temperature cycling, and high vacuum all come into play. Power sensors must perform flawlessly under these conditions without contaminating the chamber through material outgassing. This application card provides a new practical solution to ensure reliability in power measurement tasks.
