The below figure shows the typical variation of carrier to noise spectral density due to intermodulation (C/No)Im as a function of
input back-off (IBO). The model defines IBO as the carrier power at the input of the amplifier normalized by the saturation input power
(Pi/Pisat). The variable gain amplifier will evaluate this function for a computed IBO, in order to the determine the (C/No)Im.
The noise temperature due to intermodulation is then computed by dividing the carrier power by the (C/No)Im times Boltzmann's constant.
