The process will build a solid background for advanced study in high frequency circuit design. Important concepts of high frequency amplifier design such as S-parameters, maximum power transfer theorem, and input/output matching circuits, are also introduced.
In order to help readers well understand high frequency amplifier design, we start from the design of low frequency amplifiers in kHz range, and then medium frequency amplifiers in MHz range, and finally get into the design of high frequency amplifiers in GHz range. We introduce three useful impedance matching methods to help readers catch the core idea and techniques of impedance matching. Impedance matching is indispensable in high frequency circuit design, which is widely used to avoid reflection and achieve maximum power transfer.
We provide abundant examples of Smith chart with details in various applications to help readers learn how to apply Smith chart in different cases. We introduce the motivation of Smith chart in a heuristic way, and show how to build it step by step, so that readers can have an insightful understanding of Smith chart. The Smith chart is a powerful graphical tool and mastering the Smith chart is essential to entering the world of RF and microwave circuit design as all practitioners use this as if it is well understood by others. Smith chart is the most fundamental and important tool in high frequency circuit design.
