‘Load pull’ involves the systematic varying of the impedances presented to a device under test while measuring the device’s performance. For R&D applications, load pull is an essential characterization tool that allows designers to understand better the capability of their devices, to model the performance of their devices, and to design ideal matching networks. For pre-production and production applications, load pull is useful in determining a device’s robustness and resilience to mismatch and high-VSWR conditions.
Modern load pull solutions based on vector-receivers such as those found in commercial network analyzers allow for the direct measurement of calibrated a- and b-waves at the DUT reference plane. From these waves, it is possible to directly measure large signal input and output impedances as well as calculate available and delivered input power, output power, transducer and power gain, drain and power added efficiencies, and vector-parameters such as AM/PM and droop.
When combined with Maury Microwave’s LXI-certified automated impedance tuners and IVCAD measurement and modeling device characterization software, Keysight Technologies’ M9485A PXIe multiport vector network analyzer with direct receiver access becomes the first commercially available modular solution for high-frequency load pull characterization for R&D, pre-production and production applications.
The M9485A is ideally suited for vector-receiver load pull due to its improved accuracy, fast speed, high dynamic range and extreme stability. In addition, it offers best-in-class performance for advanced multiport vector network analysis, with the possibility to expand up to 12-ports in one chassis or 24-ports in two chassis.

Starting with this solution, Keysight’s modular form factor can now be considered for advanced device characterization in the same manner as benchtop instruments.Add-ons are available from Maury Microwave to extend the solution to include pulsed-RF, pulsed-bias, active- and hybrid-active tuning, and harmonic load pull.
