Wideband Load-Pull Measurement Techniques: Architecture, Accuracy, and Applications

This talk focuses on load-pull measurements for wideband communication applications. We will discuss the architecture and the design aspects of a state-of-the-art load-pull measurement system which enables wideband impedance control with complex modulated signals both at RF and baseband frequencies. We will present several application examples, ranging from high speed load-pull for technology evaluations and power amplifier design to modulated testing for 5G applications. Finally, we will describe a procedure for evaluating traceable uncertainty of power measurements as a function of the load impedance.
