5 Best Free Online Tools For Wireless Researchers

Remember: The noise figure is defined as the value of the signal-to-noise ratio at the input of the cascade, divided by the signal-to-noise ratio at its output you can find the ratio with the help of Cascaded Noise Figure Calculator.
In terms of Noise figure, F = Tn/290+1, F is the noise factor (NF = 10 * log(F))Thus, Y = ENR/F+1. In this equation, everything is in linear regime, from this we can get the equation above.

What is RF cascade analysis?

Cascade analysis is a simple but powerful tool for analyzing system behavior. You can analyze small-signal gain and noise statistics more closely, and get closer to modeling large-signal performance, such as predicting a single dB compression point.
Antenna gain is defined as the degree of directivity of the antenna’s radiation pattern. It is equal to the product of the antenna’s electrical efficiency and directivity click for Antenna Gain Calculator.

GdB = 10 log10 (4πηA/λ2)
  1. GdB is the antenna gain,
  2. η is the efficiency,
  3. A is the physical aperture area,
  4. λ is the wavelength of the signal.
    you can convert noise factor to noise figure with the help of Noise Temperature to Noise Figure Converter
    In terms of Noise figure, F = Tn/290+1, F is the noise factor (NF = 10 * log(F))Thus, Y = ENR/F+1.
