Radio Frequency and Microwave Power Amplifiers are finding an increasingly broad range of applications, particularly in communications and broadcasting, but also in the industrial, medical, automotive, aviation, military, and sensing fields. Each application has its own design specifications, for example, high linearity in modern communication systems or high efficiency in broadcasting, and, depending on process technology, capability to operate efficiently at very high frequencies, such as 77 GHz and higher for automotive radars. Advances in design methodologies have practical applications...
