abcd matrix
Hi all,
Suppose I have a two-port non-symmetric passive network whose S-par is Sx=[S11,S12;S21,S22]=[S11,S12;S12,S22].
Let's say the ABCD matrix of this network is Ax=[A,B;C,D].
If I rotate the device 180 degree, meaning port2 becomes port1 and vice versa, then the S-parameter would be Sy=[S22,S12;S12,S11]. Hence, the ABCD matrix would then be Ay=[D,B;C,A].
Am I missing something here?
In the "Microwave Engineering" by David M. Pozar book, it is written that Ay=inverse[Ax].
