When an RF Engineer starts designing a circuit, there comes a time where s/he encounters s-parameters. Looking at that s/he needs to make a call on the different other parameters like h-, Z-, T- or Y-.
Is there a tool which does it for you?
YES, there is !!
A web based calculator which can do the conversion of S-Y-Z back and forth.
How does it do that ?
The formulae which allow us to go through with the rigour needed are available in most texts and scholarly articles.
But for the people in the MATLAB zone, there is the RF ToolBox which has the s2z converter function to do the needful.
Hey, hello !! Hold on!! What are you talking about ?
The 2-port network shown above is representative of that implied
in the application of these equations.
All of the parameter equations make use of complex values for all numbers of impedance and the resulting matrix parameters, i.e., Z = R ± jX.
Z01 and Z02 are the complex impedances of ports 1 and 2, respectively; similarly, Z*01 and Z*02 are the complex conjugates of the respective impedances.
