Hi all,
Could anyone know the conversion of 4-port s-parameter to mixed mode parameter?
the case is that I have a differential in (2 ports) and differential out (2 ports) unit. I measured the 4 port s parameter into a S4p file. This s4p is measured on a 50Ohm system. I need to convert it to the mixed mode s-parameter on 200 ohm, what can i do?
I find the equation for 50ohm to 50 ohm conversion, but can't find the equation for the conversion between different impedance.
thank you for you reading.
