Modeling Devices with S-parameters

Modeling Devices with S-parameters Scattering parameters or S-parameters for short, are the standard way to describe the behaviour of all kind of RF devices. Both passive and active. So, what are these parameters and why are they so popular? In order to fully grasp the full potential of S -parameters, it is useful to lay down some basic concepts first. (Note: some understanding of transmission line theory is helpful when reading this article) 1. Concepts The basic idea behind S-parameters is to look at a device (or more generally, a netwo [...]  Read more >
