Hello,
I have a formula that determines the insertion loss of an attenuator I built. It is frequency dependent. I was wondering if anyone had an idea on how I could create a component that is modeled by this. The formula is for IL only, not S-Param. I have a data set for frequencies I need. Is there any way to make a frequency dependent attenuator?
Thank you,

Good Morning,
That was an example for impedance. Since I have the insertion loss, would it be accurate to use S2P with s12 and s21 being reciprocals of each other and s11 and s22 to be a perfect match (-100 dB)? Since it is IL and not impedance I do not believe I could use the impedance component. I cannot find an attenuator_eqn component or anything similar. Thanks again for the help!

Ended doing this, Used IL as S12 and S21 with a deg shift based off of the frequency and cable length. Used -100 for s11 s22 with 0 deg shift. Its a rough sim and does not really matter. f there is anything wrong with these assumptions please let me know. Thanks!
