Hi
In all RF books is written that RF signal with variable envelope produce much more intermodulation distortion than signal with constant envelope. Why? If we look on for example class C PA independently of envelope level ( small, big, variable) a bias point move through initial nonlinear piece of input characteristic of transistor.
