A Class C amplifier typically uses less than fifty percent of the input signal … WebFeb 14, 2024 · The collector current of a class C amplifier is a half-sine wave. Class C power amplifier is a type of amplifier where the active element (transistor) conduct for less than one-half cycle of the input signal. Less than one-half cycle means the conduction angle is less than 180° and its typical value is 80° to 120°. subscapularis tear rehab
