Pasternack's Cascaded Noise Figure Calculator computes the total noise and gain of cascaded amplifiers.
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. The lower noise figure number, the better. Visit Pasternack's RF amplifiers page for product details.
**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.
