Thanks for the clarification. So one more question. :^)
In this context what is your definition of "low frequency"? did you use a ratio from your max operating frequency? or some other factor?
Thanks for sharing that reference. Had not seen nor used that before.
I did not think of TDR. Will try this in simulation on ADS. So yeah from Zline = sqrt {L/C) only one unknown that can be solved for.
BTW, why do you limit calculating C shunt from low frequency? With the method shown in...
Current DUT does not allow us to do a 2 port measurement. However, it may be possible but need to look further into the probing and test fixture requirements to be able do do so.
Do you have any white paper and/or links that detail how to separate RLC strictly from S11 and S12 measured data...
The goal is to try to characterize a Microstrip trace on a substrate and to extract RLC from S11 measurements with the far end Open Circuit. However I am thinking the experiment setup is is not correct.
The trace is open ended so the S11 measurement is into an open. I think only Capacitance may...
Yeah, I can now see that using ideal elements in the schematic. C always shows negative ipart while L shows always positive ipart.
What confused me is that I expected this trace to be more inductive but based on the plot from my DUT it is seen as Capacitve (up to that frequency)
So, Will it...
Yeah, I had tried that but had made a mistake that I just noticed. Since my DUT is open ended when I did the schematic with lumped/ideal Capacior/inductor I left the Ideal lumped L or C without ground. Once they are porperly terminated. I can see the known value from the schemtic in the table...
Hi,
I have an s-parameter file from a measured passive structure from a VNA. I have used equations in ADS to generate Inductance and Capacitance from Impedance and Admittance of the measured s-parameters. The Capacitance is in the ball park with expected values. however the Inductance is not...
