Education in the science of RF and microwave engineering consists of guiding the reader along a gradient of known data, with the highest attention to the basic concepts that form the foundation of this field of study. The basic concepts presented in this book are far more fundamental than the mother sciences of engineering (i.e., physics and mathematics) and cover the essential truth about our physical universe in which we live. These basic truths convey a much deeper understanding about the nature of the physical universe than has ever been discussed in any RF and microwave, or for that matter any scientific textbook.
These basic truths set up a background of discovered knowledge by mankind, against which a smaller sphere of information (i.e., RF and microwave engineering) can be examined. Many of the principles that appear in microwave books are easily describable and thus understood much better once the basic underlying concepts are grasped.
While studying sciences and engineering at the university, the author always looked for simplicity, a higher truth, and a deeper level of understanding in all of the rigorous mathematics and many of the physical laws that were presented. Upon further investigation, the underlying principles that form the backbone of all extant physical sciences have finally emerged and are presented as the fundamentals of physical sciences in Chapter 1 of this work.
A summary of philosophical formation of this work is presented in the form of a pyramid in Chapter 1. From this pyramid, we can see that workable knowledge is like a pyramid, where from a handful of common denominators efficiently expressed by a series of basic postulates, axioms, and natural laws, which form the foundation of a science, an almost innumerable number of devices, circuits, and systems can be thought up and developed. The plethora of the mass of devices, circuits, and systems generated is known as the application mass, which practically approaches infinity in sheer number. This is an important point to grasp, because the foundation portion never changes (a static) while the base area of the pyramid is an ever-changing and evolving arena (a kinetic) where this evolution is in terms of new implementation techniques and technologies.
Following this brief introduction, the fundamental laws and basic principles of electrical engineering, which most advanced textbooks take for granted, are discussed. The reason for their presentation at this early stage, is that in dealing with the subject of RF and microwave engineering, it has been found that a lack of deeper understanding of these fundamentals leads to a shallow perspective and a lack of appreciation of electrical engineering basics, which will eventually lead to serious miscomprehension and misapplication of the subject.
This book is written with emphasis on fundamentals and for this reason all new technical terms are thoroughly defined in the body of the text as they are introduced. This novel approach is based upon the results obtained in recent investigations and research in the field of education, which has shown that the lack of (or the slightest uncertainty on) the definition of terms poses as one of the most formidable obstacles in the reader's mind in achieving full comprehension of the material. A series of uncomprehended or misunderstood technical terms will block one's road to total comprehension and mastery of the subject. This undesirable condition will eventually lead to a dislike and total abandonment of the subject.
The initial motivation was to bring the basics to the forefront and orient the reader in such a way that he or she can think with these fundamentals correctly. This eventually led to writing the first manuscript several years ago and then the final preparation of this book at present.
In preparing this book, the emphasis was shifted from rigorous and sophisticated mathematical solutions of Maxwell's equations and instead has been aptly placed on RF and microwave circuit analysis and design principles using simple concepts while emphasizing the basics all the way.
This book is intended to be used in a 2-semester course in microwave electronics engineering for senior-level or graduate students and should serve as an excellent reference guide for the practicing RF and microwave engineer in the field as well.
The current work starts from very general postulates, considerations and laws and, chapter by chapter, narrows the focus to very specific concepts and applications, culminating in the design of various RF and microwave circuits. The book, divided into five parts and 21 chapters, develops and presents these chapters with the progressive development of concepts following the same pattern as presented in the pyramid of knowledge in Chapter 1, which is:
Part I The Highest Fundamentals
Chapters 1- 4 form the foundation of electronics.
Part II Wave Propagation in Networks
Chapters 5-8 present the basics of RF and Microwave science, wave propagation, and network characterization concepts.
Part III Passive Circuit Design
Chapters 9-11 deal with the Smith Chart and its numerous applications to matching circuits.
Part IV Basic Considerations in Active Networks
Chapters 12-14 discuss the basic considerations of circuit design.
Part V Active Networks: Linear and Nonlinear Design
Chapters 15-21 provide detailed analysis and design methodologies of linear and nonlinear active circuits.
A list of symbols used in each chapter and a series of problems are included at the end of each chapter to help the reader gain a fuller understanding of the presented materials. The book ends with a glossary of technical terms and several important appendixes. These appendixes cover physical constants and other important data needed in the analysis or design process, with one appendix fully devoted to several design examples of practical active circuits using computer-aided design techniques based on the "Libra/touchstone" ? software Ver. 6.1 from HPEEsof.
Foreword by Dr. Asad Madni, C. Eng., Fellow IEEE, Fellow IEE
Learn the fundamentals of RF and microwave electronics visually, using many thoroughly tested, practical examples
RF and microwave technology are essential throughout industry and to a world of new applications-in wireless communications, in Direct Broadcast TV, in Global Positioning System (GPS), in healthcare, medical and many other sciences. Whether you're seeking to strengthen your skills or enter the field for the first time, Radio Frequency and Microwave Electronics Illustrated is the fastest way to master every key measurement, electronic, and design principle you need to be effective. Dr. Matthew Radmanesh uses easy mathematics and a highly graphical approach with scores of examples to bring about a total comprehension of the subject. Along the way, he clearly introduces everything from wave propagation to impedance matching in transmission line circuits, microwave linear amplifiers to hard-core nonlinear active circuit design in Microwave Integrated Circuits (MICs). Coverage includes:
Dr. Radmanesh has drawn upon his many years of practical experience in the microwave industry and educational arena to introduce an exceptionally wide range of practical concepts and design methodology and techniques in the most comprehensible fashion. Applications include small-signal, narrow-band, low noise, broadband and multistage transistor amplifiers; large signal/high power amplifiers; microwave transistor oscillators, negative-resistance circuits, microwave mixers, rectifiers and detectors, switches, phase shifters and attenuators. The book is intended to provide a workable knowledge and intuitive understanding of RF and microwave electronic circuit design.
Radio Frequency and Microwave Electronics Illustrated includes a comprehensive glossary, plus appendices covering key symbols, physical constants, mathematical identities/formulas, classical laws of electricity and magnetism, Computer-Aided-Design (CAD) examples and more.About the Web Site
