Vector receiver load pull, also referred to as real-time load pull, has become the preferred load pull methodology of the 2010s and 2020s. Vector receiver load pull replaces a traditional scalar power meter and spectrum analyzer with a vector receiver, such as a VNA. Instead of measuring powers and de-embedding to the DUT reference plane, this methodology uses low-loss couplers between the tuners and DUT to sample the a1, a2, b1 and b2 waves at the DUT reference plane to calculate delivered input power, output power, power gain and PAE. Advantages of this method include a general dynamic range improvement as well as empowering the measurement of AM/PM, large-signal input impedance, and the independent fundamental and harmonic powers and impedances.

In this webinar, we will:
• Understand the motivations of performing load pull measurements.
• Learn how to configure a vector receiver load pull bench.
• See a demonstration of vector receiver load pull using a Maury Microwave XT-series automated impedance tuner, Maury/AMCAD IVCAD measurement and modeling device characterization software suite, and Copper Mountain Technologies’ Cobalt-series VNA.
