Two-Port Parameter Converter
Convert between S, Z, Y, and ABCD (transmission) parameter matrices for a 2-port network. Enter the 4 complex parameters of one type and all other representations are computed instantly. Real and imaginary parts for each element.
Equations & Parameters ▸
| S | Scattering parameters — measured at RF with a VNA. S11=ΓIN, S21=forward gain. |
| Z | Impedance parameters — open-circuit driving-point/transfer impedances. |
| Y | Admittance parameters — short-circuit. Y = Z⁻¹. |
| ABCD | Transmission (chain) matrix — cascade by multiplying matrices. Used for filter/transmission line analysis. |
