This nonlinear behavior from the amplifier is described in numerous ways, and finally manifests as both equally degraded sign high quality and lawfully limited signal leakage into adjacent channels, as explained by the Adjacent Channel Energy Ratio (ACPR).

When it comes to the efficiency, website existing consumption, or warmth dissipation of an amplifier it is vital to look at the enter energy that could be viewed through the amplifier and history the DC current at that enter electrical power and frequency.
