A Technical Foundation for RF CMOS Power Amplifiers: Part 4: Misunderstandings in PA Design

摘要

This fourth part of the article series "A Technical Foundation for RF CMOS Power Amplifiers" [1] presents five misunderstandings regarding wireless signals and amplifier design that persist in the literature and generally cause confusion, particularly for engineers new to this art. Each of these misunderstandings is addressed for its realistic answer along with additional discussion about why addressing that misunderstanding matters. At the end, four fundamental technical foundations are identified that can reliably be used to check and validate ideas and approaches during design and development projects.
