APPLICATION NOTE 2875
Three Methods of Noise Figure Measurement
Three different methods to measure noise figure are presented: Gain method, Y-factor method, and the Noise Figure Meter method. The three approaches are compared in a table.
Introduction
In wireless communication systems, the "Noise Figure (NF)," or the related "Noise Factor (F)," defines the noise performance and contributes to the receiver sensitivity. This application note describes this important parameter and details ways to measure it.
Noise Figure and Noise Factor
Noise Figure (NF) is sometimes ieferred to as Noise Factor
