Load Pull is the act of presenting a set of controlled impedances to a device under test (DUT) and measuring a set of parameters at each point. By varying the impedance, it is possible to fully characterize the performance of a DUT. The most common tool used to vary the impedance presented to a DUY is the passive impedance tuner. While the fundamental principles of passive impedance tuning haven’t changed significantly since their earliest conception, today’s state-of-the-art automated impedance tuners have improved accuracy and repeatability, are orders of magnitude faster, allow for direct user control, and are optimized for on-wafer measurements.

In this webinar, we will:
• Understand the motivations of performing load pull measurements.
• Learn how passive impedance tuners work (coaxial fundamental and harmonic, waveguide…).
• See a demonstration of state-of-the-art impedance tuner technology at 5G FR1 and FR2 frequencies.
