Noise Figure • Temperature Conversion
... converts between noise figure and the noise temperature.
✈ Some background
Noise temperature is the temperature at which a resistor (or other component) would generate the same
amount of noise. It goes back to the familiar kTB calculation for thermal noise
power.
It comes in handy at e.g. antennas, where it is hard to define a NF (noise-figure).
The formulas used are :
Note that the Reference Temperature is usually 290 K. (= 273.15 (Zero) + 16.85 (RTP)).
