Tips for Making Successful Noise Figure Measurements

Noise figure is often the key to characterizing a receiver and its ability to detect weak incoming signals in the presence of self-generated noise. The process of reducing noise figure begins with a solid understanding of the uncertainties in your components, subsystems and test setups. Quantifying those unknowns depends on flexible tools that provide accurate, reliable results.

The 10 hints presented here will help minimize the uncertainties in your noise figure measurements - whether you are designing for good, better or best performance in your device. Key topics include minimizing extraneous signals, mismatch uncertainties, nonlinearities, and path losses.
