Cascaded Gain and Noise Figure Calculator

rf microwave noise figure cascaded gain amplifier system gain calculator

This page provides tools for calculating cascaded gain and cascaded noise figure. We offer both a cascaded gain calculator and a cascaded noise figure calculator.

The cascaded gain calculator determines the overall gain of a 3-stage amplifier system.

The cascaded noise figure calculator computes the aggregate noise figure for a 3-stage amplifier system.

Example: Cascaded Gain and Noise Figure Calculation

Inputs

Outputs

Let’s illustrate with an example using the calculators.

INPUTS (Linear values):

  • G1 = 10
  • F1 = 1.4
  • G2 = 10
  • F2 = 2
  • G3 = 25
  • F3 = 3.6

OUTPUTS:

  • Cascaded Gain = 33.97 dB
  • Cascaded Noise Figure = 1.83 dB
