Calibrated Multiport Large-Signal Measurement Setups for Outphasing, Doherty and Load Modulated Balanced Power Amplifiers

This talk will present several multiport large-signal measurement setup based either on VSG/VSA or on NVNA. The architecture of those benches will be discussed, then new calibration methods for multiport devices will be presented. Finally the presentation will offer some measurement examples on multiple-input power amplifiers : “Outphasing”, “Digital Doherty” and “Load Modulated Balanced” RF Power Amplifiers.
