WebThe gain given by the data sheet of the SHF amplifier is only valid for the linear region of the amplifier. Above certain input power levels the amplifier gets into compression and the gain P Out /P In is actually less than for input signals with lower power level.. To quantify this amplitude non-linearity, SHF specifies the compression points.

WebClass D amplifiers are not digital in the true sense. They are not driven directly by coherent binary data. They do act digitally in that the output drivers operate either in the fully ON-region or fully OFF-region. Think of Class D amps as being similar to a switch-mode power supply, but with audio signals modulating the switching action.
