Port reference impedance
WebApr 16, 2013 · With lumped ports you should know the characteristic impedance of the connected feeding line for calculating S-matrix, while with wave ports, if correctly sized, portZ0 defines the reference impedance for calculating S parameters, and it automatically takes the value of the Zo impedance of feeding line. Webgenerator connected to port 2 and the load to port 1. Fig. 14.1.3 Two-port network under test. The two line segments of lengths l 1,l 2 are assumed to have characteristic impedance equal to the reference impedance Z 0. Then, the wave variables a 1,b 1 and a 2,b 2 are recognized as normalized versions of forward and backward traveling waves. Indeed,
