Noise figure describes how much extra noise an RF device adds to a signal path. Lower noise figure means better receiver sensitivity and cleaner signal performance.
Noise temperature is another way to express the same noise contribution, commonly used in RF receiver, antenna, and microwave system calculations.
Input Example
Noise Figure: 1.5 dB Reference Temperature: 290 K
How to Use
Select NF dB to calculate noise temperature, or select Temp K to convert noise temperature back to noise figure.
