   Class C amplifiers present higher efficiencies than class A, B or AB. However, their conduction angle is very low between 0° and 180°, meaning that they conduct only a fraction of the signal. This fact leads to a poor linearity of the amplifier, both voltage and current outputs are very distorted because they present a high number of harmonics.

   The class-C amplifier has two modes of operation: tuned and untuned. The diagram shows a waveform from a simple class-C circuit without the tuned load. This is called untuned operation, and the analysis of the waveforms shows the massive distortion that

   2014年1月9日 · 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°.

   Class A amplifiers have the highest linearity and Class B and C amplifiers result in considerable distortion. As a compromise, Class AB amplifiers are used in many cellular applications, although Class C amplifiers are used with constant envelope modulation schemes, as in GSM.

   The Class C Amplifier design has the greatest efficiency but the poorest linearity of the classes of amplifiers mentioned here. The previous classes, A, B and AB are considered linear amplifiers, as the output signals amplitude and phase are linearly related to the input signals amplitude and phase.

    What is the conduction angle of a Class C amplifier?

    • However, the class C amplifier is heavily biased so that the output current is zero for more than one half of an input sinusoidal signal cycle with the transistor idling at its cut-off point. In other words, the conduction angle for the transistor is significantly less than 180 degrees, and is generally around the 90 degrees area.

    What is the difference between Class C and class AB amplifiers?

    • With the Class C amplifier there must be some positive RF input signal before there is an output: there is more distortion but no current flows, not even leakage current, when there is no RF input signal. The Class AB amplifier is a compromise between Class A and Class B amplifiers.

    How does a Class C amplifier work?

    • The Class C amplifiers used in RF transmitters usually are operating at a single fixed carrier frequency. In such applications, the distortion is controlled by a tuned load on the amplifiers. The input signal is applied to switch the active device (transistor) and so the current is directed to flow through a tuned load. Fig 3.
