The Fundamentals for Linear and Low Noise Amplifier Designs with Mouqun Dong

When Artech House authors write their books, we ask them what they want their readers to get out of the project. In this series, we show you what our authors, in their own words, wish to impart upon readers. Mouqun Dong, author of RF Circuits and Applications for Practicing Engineers, describes what his book is about:

This book is about the theory of RF circuits and systems and the practice of designing them.

It is primarily intended for practicing RF engineers, especially those who are involved in wireless circuit and system designs, particularly for two groups of readers:

  • Engineers who are equipped with sufficient educational knowledge, but are relatively new in the field. To them, it is not always straightforward how the textbook materials can be used in an actual product design and development process;
  • Experienced engineers with a great deal of practical knowledge but who may need a “brush-up” on the theory behind the practice.

The book can also be used as a supplementary material for college students taking a course on RF and microwave engineering.

By emphasizing the relevance to practical designs, this book distinguishes itself from typical textbooks that focus on teaching RF circuitry as an academic subject matter. The basic concepts and techniques covered in this book are those that are routinely used in today’s engineering practice, especially from the perspective of the PCB based RF circuit design and system integration. At the same time, the book is not written as a practical handbook either. Sufficiently detailed discussions on the chosen topics are provided so that the reader can see why they are important and how they are applied in practical circuit designs. Many examples from real-world engineering practice, including real tested circuits and other people’s mistakes, are presented throughout the book. Various practical tips in circuit designs and measurements, that might be deemed either too technical or too trivial for textbooks, are described in length.  In addition, whenever pertinent, technical issues are always discussed in quantitative terms, and possible trade-offs among different design considerations are explained. The intention is to help the reader to develop a numerical feel for RF problems as well as awareness of the concepts of design for cost and design for manufacturing, which is a critical skill set for today’s engineers working in an environment of commercial product development.  Finally, for a selected few topics that are important conceptually but are not normally covered in textbooks, such as stability criteria and the invariant property of lossless networks, the book presents detailed theoretical treatments. They are mainly for analytically oriented readers.

A comprehensive breakdown of the book:

The book is organized as follows. The first four chapters cover the fundamentals for linear and low noise amplifier designs, including the S and noise parameters and their applications in amplifier designs and matching network designs using the Smith chart. A number of practical design issues are described in Chapter 5 in great detail. Chapter 6 and 7 are on theories of RF power amplifiers and high efficiency power amplifiers respectively. Chapter 8, which is for RF engineers working on wireless products, introduces some basics of wireless communications systems. Passive components commonly used in RF circuits and measurements is discussed in Chapter 9. Chapter 10 is about RF measurement techniques. The last chapter is on RF switches.  Subjects on some important RF components in wireless systems, such as oscillators, mixers and filters, are not covered in this book because they are either integrated into transceiver ICs in most applications (oscillators and mixers) or manufactured as a stand-alone components (filters).
