s6p to s2p RF toolbox

Hello I have a .s6p file, gotten from a electromagnetic simulation of a dual tapped transformer, but I want to convert this s6p file to a s2p file, with 2 differential ports and the center taps grounded. Also I have a problem with a s5p file (single-tapped transformer) and I want to convert it into a s2p file as well, with 1 differential port, 1 single ended port, and the rest of the ports grounded. Thank you

Hi Jeffrey,

Converting “.s6p” and “.s5p” files to “.s2p” files involve a process called port reduction or network consolidation. This process typically requires the use of specialized RF simulation or analysis software. However, on a conceptual level, to perform the conversion, you typically need to:

1. Load the S-parameters from the “.s6p” or “.s5p” file into your RF simulation software.
2. Define the new network by specifying which ports are grounded, which are differential, and which are single ended.
3. Use matrix operations (such as concatenation and reduction) to derive the new S-parameters for the “.s2p” file. This often involves complex mathematical operations that consider the interactions between all ports.
4. Export the new S-parameters to a “.s2p” file.

Since this is a complex process that typically requires specific software tools and a deep understanding of RF network theory, here is a link to the documentation for the steps and commands to perform this conversion:

Hope this helps!
