Arguments
Input arguments
# y_params — N-port Y-parameters
+
N×N×M array
Details
-port Y-parameters specified as an array of size on on , where represents the number of frequency points -port Y-parameters.
# Z0 is the calculated impedance, ohms
+
50 | positive real scalar | positive real vector
Details
The calculated impedance in ohms is set in one of the following ways:
-
Positive real scalar, if you want to set the same calculated impedance for all network ports.
-
A positive real vector of length if you want to set a different design impedance for each port in - port network.
-
A positive real vector of length if you want to set a different design impedance for each of the frequencies in the data.
If the calculated impedance is a vector, and the number of ports equal to the number of data frequencies , , then the function sparameters will assign each element of the vector to each port of the network. To specify the calculated impedance for each frequency in this case, specify Z0 as a three-dimensional vector of size on on .
Output arguments
# s_params — N-port S-parameters
+
N×N×M array of complex numbers
Details
-port S-parameters returned as an array of complex numbers of the size on on , where represents the number of frequency points -port S-parameters.
Examples
Converting Y-parameters to S-parameters
