Let us assume a 50Ω Source feeds a 2-port network #1, which is followed by a 2-port network #2, which is terminated into 50Ω. The (modified) input reflection coefficient $s’_{11}$ of the (output-mismatched) network #1 is $$s’_{11} = s_{11} + \frac{s_{21}s_{12}\Gamma_{L}}{1-s_{22}\Gamma_{L}}$$ with (complex) s-Parameters of network #1, and $\Gamma_{L}$ for ...
