Noise Figure to/from Noise Temperature Calculator
Noise figure to/from noise temperature calculator from Pasternack will produce either noise figure or noise temperature, depending on the input type.
When looking at noise figure (NF) calculator output, it measures degradation of the signal-to-noise ratio (SNR), caused by components, such as amplifiers, in an RF signal chain. The noise figure number, displayed in decibels (dB), represents the performance by which an amplifier or RF receiver can be measured.
For the noise temperature calculator, it is a representation of noise in terms of the temperature required to produce an equivalent amount of Johnson-Nyquist Noise.
