S-Parameters

I've been sent a white paper from RF-globalnet on S-parameter extraction. For those of you who do not know what a S-parameter is, I shall recommend to read it. For the rest, it can be interesting reading another point of view. The paper is from Richard Wang, Applications Engineering Manager, RF Micro Devices, Inc., and Ming-Hsiang Cho, Ph.D. Candidate, National Chiao-Tung University (Taiwan). You can download it from this link (it's free!).

Hint: S-parameters are used in RF circuits...
