A Time Domain Envelope Vectorial Network Analyzer for Non-linear Measurement Based Modeling Accounting Impedance Mismatches

This paper presents a measurement setup which enables power amplifier characterization driven by radio frequency modulated signals. Incident and reflected absolutes waves at both ports of the device under test can be measured even in a source pull or load pull environment. The structure and the calibration procedure of the setup are explained. Measurements examples are shown and then used in order to generate a new kind of complex envelope behavioral model. This model is taking into account both high frequency memory effect and loading impedance mismatch
