Calculating Mismatch Uncertainty

Read Tony Lymers article published on the Microwave Journal website discussing the calculation of Mismatch uncertainty. Mismatch uncertainty is a very common and often underestimated source of error in microwave power measurements. It arises from an incomplete knowledge of the phase of the reflection coefficients of the source and load impedances, plus their interconnection, and is usually a large component of the overall measurement uncertainty budget in a microwave power transfer. It is easy to estimate and should not be ignored.
