RF Behavioural Modelling Using Multisine Excitations
Kate Remley, Dominique Schreurs
Large-signal behavioural models for RF devices have historically been based on single- or two-tone data. This type of excitation is often not very representative, as RF devices, being used in telecommunication systems, are usually subjected to modulated excitations. In this chapter, it is shown that the use of multisine excitations (as approximation of modulated signals) can render the modelling more efficient from both the experiment design and data handling points of view, and this without loss of accuracy. In addition, as modulated excitations can reveal slow-memory effects present in the device, it is described how these can be incorporated in the behavioural modelling description.
