The Noise Figure to Noise Factor Calculator makes it easy to convert an RF device’s noise figure (in dB) to a linear noise factor.
This tool is useful for engineers and technicians working on the design and analysis of RF systems and amplifiers.
Formula used
F = 10^(NF / 10)
Or :
NF = noise figure in dB
F = linear noise factor
Explanation
The noise figure (NF) expresses the noise added by an RF component in decibels.
The noise figure (F) is its linear version, useful for calculations of overall performance of RF systems.
The conversion is done by raising 10 to the NF power divided by 10.
A lower NF corresponds to an F closer to 1, which indicates a quieter component.
Calculation example
For an amplifier with NF = 3 dB :
F = 10^(3 / 10) ≈ 2.0
Benefits and Use
- Allows you to quickly convert the noise figure into a linear noise factor.
- Useful for sizing amplifiers and RF systems.
- Helps compare components and optimize system performance.
