Abstract:
|
An analysis of the problem of noise parameter determination is carried out. It is found that the mathematical problem is ill-posed if all the source reflection coefficients (Γs) used in the measurements fall onto a line, circle or are of a circle in the Smith chart. This is used to expand on existing criteria for selecting Γ s and to rule out sources of accuracy degradation. |
