Calculate the mixed-mode S-parameter from an S4P file
Answer
The single-ended S-matrix
and the mode conversion matrix
and the relation for the mixed-mode matrix
yield
The mode conversion matrix M delivers the mixed mode in the order 1d, 1c, 2d, 2c.
The numbers refer to the logical port number where d is differential and c is common mode.
The mixed- mode S-parameters in this matrix are as follows:
