Dear All,
I want to desing a transformer as a power combiner (2 primary Inductors and 1 secondary inductor).
as I expect there are three ports which result 3 port Z-Network.
How I calculate the parameters of this transformer (Lp1, Lp2, Ls, Mutual Inductance (M), coupling factor (K) and insertion Loss(IL))
----------------------------------------
Lp1=imag(Z(11))/(2*pi*Freq) ..... 1st Port
Lp2=imag(Z(22))/(2*pi*Freq) ..... 2nd Port
Ls=imag(Z(33))/(2*pi*Freq) ..... 3rd Port
are these equation correct؟
what about M, K, and IL
any help is highly appreciated.
Regards
