This converter can be used to convert noise temperature to noise figure.

Input Parameters

Calculation Result

Calculation Formula

NF(dB) = 10 * log(1 + (T_noise / 290))

Where:
NF(dB) is the noise figure in decibels.
T_noise is the noise temperature in Kelvin.
290 K is the standard room temperature.

Working Principle

The noise figure is a measure of the degradation of signal-to-noise ratio (SNR) caused by components in a radio frequency (RF) signal chain. The noise temperature is a way to express the amount of noise generated by a component. This calculator converts the noise temperature to a noise figure using the formula mentioned above.
