Noise Figure - Noise Temperature Calculator

Pasternack's Noise Figure - Noise Temperature Calculator will produce either noise figure or noise temperature, depending on the input type.

Noise Figure:

Noise figure (NF) measures of 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.

Noise temperature is a representation of noise in terms of the temperature required to produce an equivalent amount of Johnson-Nyquist Noise.

**Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
