Reference Temperature

NT(°K) = Tref * ( 10 ^ NF/10 - 1)
NF(dB) = 10 * Log10( NT/Tref + 1)

*Note the reference temperature is specified in °C. The default value is 16.85 equating to 290°K as per IEEE recommendations.
Noise temperature is way to express the amount of noise power introduced to a system by a component or one port source such as an antenna.
