Deciphering Amplifier Classes in Ham Radio
This chapter provides an in-depth examination of the various classes of amplifiers used in ham radio: Class A, B, AB, and C. Each class has distinct operational characteristics, efficiency levels, and applications critical to radio communications. Class A amplifiers are known for their high fidelity and continuous operation, whereas Class B and AB amplifiers offer a compromise between efficiency and sound quality. Class C amplifiers are highly efficient but are typically used in specific RF applications due to their significant distortion. Understanding these amplifiers is essential for anyone involved in ham radio, as they significantly impact the transmission quality and system efficiency.
