ABSTRACT:
This paper
investigates frequency limitations of calibration and de-embedding techniques
for S parameter measurements. First, the TRL calibration methods are analysed and the error
due to the probe movement when measuring the different line lengths is
quantified, next the coupling between the probe-heads and the wafer surface is
investigated and finally an upper frequency validity limit for the standard
Open-Short de-embedding method is given. The measured results have been
confirmed thanks to the use of an electro-magnetic simulator.
