For example, the engineering team may use one tool for error vector magnitude (EVM) measurements and another for calculating cascade noise figure (NF) and output IP3 (OIP3).
This is why the receiver cascade noise figure and sensitivity calculation is usually only done for the parts before the mismatch begins.
Using the cascade noise figure equation and the fact that the gain and noise figure in dB of the temperature compensation network are identical in magnitude but opposite in sign, the overall system noise figure is expressed as,
