WebIf the reference impedance is a vector and the number of ports N equals the number of data frequencies K, N == K, then the sparameters object will assign each element of the vector to each port of the network. To specify reference impedances for each frequency in this case, specify Z0 as a 3-D vector of length 1-by-1-by-K. WebThe characteristic impedance (Z 0) of a transmission line is the resistance it would exhibit if it were infinite in length. This is entirely different from leakage resistance of the dielectric separating the two conductors, and the metallic resistance of the wires themselves. Characteristic impedance is purely a function of the capacitance and ...

WebNov 4, 2024 · Note above that Z01 is the port 1 reference impedance, and Z02 is the port 2 reference impedance. Together, they give a comprehensive definition of channel behavior. The important point here is that the S11 parameter is not always equal to the reflection coefficient between a source impedance and the impedance of a single element. WebReference 2 has evaluated the Reference 1 equations for various geometric patterns against test PCB samples, finding that predicted accuracy varies according to target impedance. The equations quoted below are from Reference 1, and are offered here as a starting point for a design, subject to further analysis, testing and design verification.
