Cascaded Gain and Noise Figure Calculator
Advertisement
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
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
Equations and Formulas
The following equations are used in the cascaded gain and cascaded noise figure calculators:
These formulas are essential for determining the overall performance of multi-stage amplifier systems. Understanding how gain and noise figure cascade is crucial in RF and microwave design.
