Multiharmonic Generator for Large-Signal-Network-Analyzer Verification
Résumé
Since S-parameters were first used to describe linear microwave circuits in the 1960s, circuit designers, software developers, and instrument manufacturers have gradually come to an agreement on this blackbox representation, resulting in significant advancements in modeling, simulation, and measurement. As a mathematical language of high-frequency signal transmission and scattering, S-parameter stands for a unified form of the linear characteristics of microwave networks in the frequency domain. Subsequently, the vector network analyzer (VNA) was invented as the principal instrument to measure S-parameters and characterize the linear behavior of devices and components, including small-signal active circuits.
