How to: Behavioral Modeling

The design and the definition of RF systems are still being addressed from time to time using rudimentary tools such as Excel spreadsheets. However, the new signals that will be used in modern communications such as 5G will require systems to deal with very large instantaneous RF bandwidths and the basic spreadsheet approach will no longer be adequite. Indeed, these tools will not allow designers to take into account or predict the parasitic effects that will be present along the RF chain. Indeed, the observation of figures of merits such as error vector magnitude (EVM) and adjacent channel power ratio (ACPR) under modulated signal conditions requires the use of a powerful library of behavioral models associated with a system simulator. These models must represent the various circuits used within a front-end system, especially if the mismatch brought back by the antenna across the entire chain must be taken into account. This presentation will showcase the use of a new software platform dedicated to circuit behavioral modeling, which makes it possible to cover the gap between circuit simulators or the use of conventional measurement benches, and system simulators.
