skrf.network.s2y

skrf.network.s2y(s, z0=50)[source]

convert scattering parameters [1] to admittance parameters [2]

\[y = \sqrt {y_0} \cdot (I - s)(I + s)^{-1} \cdot \sqrt{y_0}\]
Parameters:
  • s (complex array-like) – scattering parameters
  • z0 (complex array-like or number) – port impedances
Returns:

y – admittance parameters

Return type:

complex array-like
