Abigail. Age: 26. Hello to you, that decided to make a moment to check out who i am The Case for Class C Jump to Amateur radio - Linear amplifiers need to operate with class-A or class-AB biasing, which makes them relatively inefficient. While class C has far higher efficiency, a class-C amplifier is not linear, and is only suitable for the amplification of constant envelope signals. Such signals include FM, FSK, MFSK, and. As amateur radio we need power, W in input and up to 2 kW ouput (that depends of your national regulation), we need a linear signal and efficiency. To get these The efficiency of a Class C amplifier is very higher, reaching 75% in best cases, but this mode generates strong cross-over distortions too. Other classes. Sindee. Age: 27. Meet me once and you will never forget me. Class C Amplifiers. You will recall that most AF amplifiers use cathode bias. The audio amplifier tubes are operated ad Class A or Class B, because we are interested in obtaining good fidelity. The Class A amplifier sacrifices efficiency for fidelity. In the case of an RF amplifier, we are not interested in fidelity, since we are not.
