Propagating Measurement Uncertainty to Microwave Amplifier Nonlinear Behavioral Models

Abstract

We propagate for the first time correlated measurement uncertainties into a nonlinear behavioral model of a millimeter-wave amplifier. We make use of the National Institute of Standards and Technology Microwave Uncertainty Framework to evaluate the uncertainties in large-signal electromagnetic wave measurements of an amplifier, followed by the extraction of Xparameters using an industry standard algorithm. This extracted model is included as a component in a circuit simulator to evaluate gain and efficiency incorporating measurement uncertainty.Index Terms-Measurement uncertainty, microwave amplifiers, microwave measurement, millimeter wave measurements, millimeter wave transistors, parameter extraction, power amplifiers.
