Résumé

Presently, there is an ever increasing demand of high efficiency and wideband microwave components and devices for wireless communication and sensing applications. However, this tendency generally pushes the devices forward to operate from linear to non-linear regions of operation. Therefore, there is a requirement of accurate measurement strategy to extract the non-linear parameters of devices [1]. Large-Signal-Network-Analyzer (LSNA) is a typical example of such measurement instruments for accurate modeling and characterization of the non-linear properties of circuits and devices [2]-[3]. LSNAs measure the relative dependence of both magnitude and phase between different orders of harmonics (including the fundamental signal) that are generated by the non-linearity of circuit. Such a non-linear model renders the circuit and system design process efficient and predictable. However, the accuracy of the non-linear parameters strongly depends upon the measurement accuracy of the LSNA itself. Therefore, the accuracy of the LSNA has to be checked and verified prior to performing the measurement of a non-linear device.
