Noise Figure Measurements: 10 Hints

Show Description

Minimizing uncertainties in your noise figure measurement is important to detect weak incoming signals. The process of reducing noise figure begins with a solid understanding of the uncertainties in your components, subsystems and test setups.

The 10 hints presented in this paper 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 how to select an appropriate noise source, guidelines for minimizing extraneous signals, methods to reduce mismatch uncertainties, how to avoid nonlinearities, account for path losses and many more.

In addition, this paper also includes a checklist to help you verify that all hints have been considered for a particular measurement. Download this paper today to learn how to make successful noise figure measurements, optimize test setups and identify unwanted sources of noise.
