skrf.network.s2z

skrf.network.s2z(s, z0=50)[source]

Convert scattering parameters [1] to impedance parameters [2]

\[z = \sqrt {z_0} \cdot (I + s) (I - s)^{-1} \cdot \sqrt{z_0}\]
Parameters:
  • s (complex array-like) – scattering parameters
  • z0 (complex array-like or number) – port impedances.
Returns:

z – impedance parameters

Return type:

complex array-like
