Nonlinear Vector Measurements and Associated Behavioral Models [From the Guest Editor´s Desk]

This issue of IEEE Microwave Magazine is focused on nonlinear vector measurements and associated behavioral models. These measurements can be seen as the higher-power extension of small-signal, vector network analyzer (VNA) measurements, where, at higher powers, there is energy transfer from the fundamental to the harmonics, and the signals are no longer sinusoidal. These behavioral models are black box models that empirically describe the behavior of a part or device with a look-up table.
