Error bounds analysis of de-embedded results in 2x thru de-embedding methods

Abstract

In this paper, an error bound analysis is performed for 2x thru de-embedding methods: AFR (Automatic Fixture Removal) and SFD (Smart Fixture De-embedding). Basically, a certain amount of error is assumed to exist in S11 of 1x. This error will cause the de-embedded results to vary within a certain range. The upper bound and lower bound of the magnitude of the de-embedded results are given.
