Alistu, I think you are referring to matrix that is available in components pdf. I found the following
attached image.
where p is the signal of the c is coupling coefficient and is the additional loss. If the parameter Conjugate is FALSE, then the relative phase shift between input port 1 and output port 2 = + 90 degrees (p is positive (value = 1), and the coupler will use the definition of [1].) When TRUE the relative phase shift between input port 1 and output port 2 = – 90 degrees (p is negative (value = -1) and the coupler will use the definition of [2].) The phase shift settings can also be viewed within Component results – Phase shift P1(In)/P2(Out) (deg)

please anyone explain in details
