RF AMPLIFIER CLASSES
2026-08-06
Choosing the right RF amplifier class requires balancing linearity, efficiency, output power, bandwidth, and other system requirements—there is no one-size-fits-all solution.
This infographic compares the four most common RF amplifier classes—Class A, Class AB, Class B, and Class C—highlighting their conduction angle, linearity, efficiency, and typical applications.
Whether you're developing RF systems for communications, test & measurement, EMC testing, or other wireless applications, understanding these trade-offs can help you make more informed design decisions.
Which RF amplifier class do you use most often, and why?
