Large signal tuned amplifier
Class C power amplifier
Class C amplifier is tuned amplifier which can amplify only a narrow
band of frequencies around the center frequency.The conduction angle is
less than 180°.The output contain lots of harmonics and these are
eliminated by using tuned circuit as load
Cc,R and Base emitter diode acts as a clamping circuits which clamps the input signal towards negative .Hence the transistor conduct only for a short duration during each positive peak of input signal .the output current Ic appears in the form of pulses .But the CE voltage will sinosuidal because of tank circuit VCE will be 180° out of phase with VBE
Power Dissipation is less
