Amplifiers

The following discussion of transistor rt power amplifiers assumes the reader knows his alphas- and betas of transistor theory. He may also !'iave had some experience with transistors in audio and small signal applications. The experience will have conditioned him to the importance of protecting transistors from excessive voltage and. heat. But transistors perform so much differently as rf power amplifiers than they do in other applications that the previous experience is not essential to understand the discussion.
