Code to Create MDIF(MDF) file from S2P and S4P File

I am trying to write a code to create a MDIF(MDF) files from the obtained S2P and S4P files. I would like to know the functions used as I am new to MATLAB.

Hi,

To create a Multi-Dimensional Interchange Format (MDF) file from S2P and S4P files in MATLAB, you can use the following functions:

rfdata.data - This is used to create an RF data object from the S-parameter data obtained from the S2P or S4P file.

This is how you can create the RF data object:

 file = 'default.s2p';
 h = read(rfdata.data,file); %Read file into data object

You may refer the official documentation to know more about the usage of ‘rfdata.data’: https://in.mathworks.com/help/rf/ref/rfckt.rfdata.data.html

You may also use the ‘sparameters’ function to obtain data from S2P or S4P file. It enables you to calculate S-parameters for a circuit object, a matching network object, an RF data, and a network.

This is how you can use the ‘sparameters’ function:

S = sparameters('default.s2p');
disp(S)

You may refer the official documentation to know more about the usage of ‘sparameters’ function: https://in.mathworks.com/help/rf/ref/sparameters.html

You can use the ‘mdfCreate’ function is used to create an MDF file. And then use the ‘mdfWrite’ function to store the necessary details you extracted from the S2P or S4P files earlier

You may refer the official documentation to know more about the usage of ‘mdfCreate’ and ‘mdfWrite’ function:

mdfCreate

mdfWrite

I hope this helps.

Thanks,

Ninad.
