Start here and watch the video. This is a presentation I did last week

Hello,
Is there a relation between the physical length being de-embedded out of a
structure (microstrip - DUT - microstrip) and accuracy of de-embedding in
the 2-20GHz range for HFSS? Is there some limitation on the
electrical length on either side of the DUT that cannot be accurately
de-embedded for this frequency range and could cause spurious spikes in the
S-parameters?


Thanks,
Nikita
