It is very simple in that it assumes that all the frequency dependence is due to skin effect and loss tangent. The loss tangent is assumed to be constant. It will work fine for any uniform transmissio

Hello All Andy, I did as suggested and eliminated the unusable LTRA sim. Thank you for your attention to this matter. Recently, Andy wrote: "I believe the Inductance value in the Cable Impedance Calcu

I quoted the wrong line from Dave Bell. I pasted this one: "... because it puts a short-circuit across an ideal voltage source." but it should have been this one: "... the Vsource is hard-coded as 0,

Thank you. I couldn't find any mention of the term anywhere, but you have explained that. ====================================================================================== Best wishes John Woodga

Awesome. Thank you for your help, and for the models.

Dear All, I'm just checking LTRA model, today again. It does not work in case of only R-C combination, still. It well works for RLC/LC/RG cases. I confirmed this issue by using ver.IV LTspice. In case

Tim, you should tell us whenever you've uploaded something relevant to your questions. I guess the file was already there, but Tony did not know. Just send a message when you know the filename. If you
