This converter allows you to transform a noise factor (expressed in dB) into equivalent noise temperature (Kelvin). It helps evaluate the amount of noise added by an RF component or system, useful for performance analysis of amplifiers, receivers and communication chains.
Formula
Tn = Tref × [ (10^(NF/10)) − 1 ]
Explanation of the formula
The noise figure (NF) indicates the degradation of the signal-to-noise ratio of a device. By converting it into noise temperature (Tn), we express this degradation in thermal form. Tref represents the reference temperature, generally 290 K. A lower value of Tn corresponds to a quieter and more efficient component.
Uses of the calculator
- Thermal noise evaluation of RF and LNA amplifiers.
- Analysis of the performance of radio and satellite receivers.
- Practical tool for designing low noise systems.
- Used in the research, design and testing of RF components.
