App-Note: 002  -  Amplifier Classification A vs. AB


Amplifiers are designed in many ways. One distinction is how the amplification devices are biased. 

They can be biased in different ways that affect performance and efficiency. This is called the Class of operation.  Class A, B, or AB are commonly used and referred to in specifications for high power RF & Microwave amplifiers. We discuss in this paper the differences between the different classifications and what it means with respect to performance. There are more classes of operation Class C, D, E… these are less common, and custom designed for individual tasks where high efficiency and linearity are not a concern.
