Generating RF filter obj from filter data

I am trying to generate an rf filter object in order to generate S parameters with the sparameter function. I have access to the exact frequency, magnitude and group delay values of an RF filter and do not want to approximate the data ideally. I am unable to find any function or any design specification within the rffilter that can allow me to create the filter from my data. Am I missing some function that can do this? is there an alternative to the rffilter that I can use to generate the s parameters from my data?
Thank you for your help.

Hi Hayden,
Based on my understanding, it seems that you are seeking guidance in generating an RF filter object using custom data. In this case, I recommend using the 'rffilter' function, which allows you to generate a rffilter object.
With the 'rffilter' object, you can specify the necessary parameters using name-value pairs as follows:
robj = rffilter('ResponseType','Bandpass','Implementation','LC Tee');
Additionally, you can utilize the 'groupdelay' and 'set' methods to set the specific parameters of the RF filter.
gd = groupdelay(robj,freq);
set(rfobj,'propertyname',propertyvalue);
By leveraging these functionalities, you should be able to create the desired RF filter object using custom data. To gain a deeper understanding of the ‘rffilter’ and its associated functions, I recommend referring to the following documentation link:
I hope you find this information useful.
