What is non linear amplifier?
In nonlinear amplifiers, the output signal is affected by various types of distortions. The amplifier nonlinearity is directly related to output signal distortions. In ideal amplifiers, signals are amplified without any change in their waveshape and we say the amplifier is of good fidelity.
Why power amplifiers are non linear?
High Power Amplifier in wireless communication systems exhibit nonlinear behavior which causes signal degradation. This is detrimental to the signals that pass through it. It appears in the form of Harmonic distortion, Gain compression, Inter-modulation distortion, Phase distortion, adjacent channel interference, etc.
