Conclusion

The receiver noise figure is an important system design parameter because it determines the weakest detectable signal. In addition to a very low inherent noise figure, the ADC32RF54 also provides a high SNR, which allows the system to maintain its noise figure even with a larger-input power signal. An ADC with same noise figure but a lower SNR would require a reduction in the input gain to prevent saturation, in which case the ADC noise figure starts adding more to the overall noise.
