The book under review is the second edition, which updates the (now more than 25 years old) first edition with two new chapters on RF Front-End Design (chapter 8) and RF Design Tools (chapter 9). Chapter 8 covers modern radio front-end design including sections on intermodulation, receiver architecture and software defined radios. Chapter 9 gives an overview of design tools before going into a detailed case study of IEEE 802.11a in CMOS using Analog Office software.
It is instructive to see both how many things have changed and yet how the basic principles have remained the same. Even though the individual NPN transistors mentioned in the original chapters are long gone (replaced by highly integrated op-amps and LNAs), the passive components are still used in designs every day. And the transistor design issues (S parameters, transistor biasing) still apply today in the multi-GHz range just as they did in the MHz range a quarter of a century ago. Today's integrated designs might include an on-chip inductor created with rectangular traces wrapped into a "coil" instead of an actual physical coil and on-chip capacitors and resistors, but the principles remain the same. In fact, the performance of passive on-chip capacitors and inductors is normally orders of magnitude worse than is required for high performance designs. Thus the physical components are still widely used today.
There are a number of RF circuit design topics missing from this book, including oscillators, distributed elements, microstrip and slot line designs for GHz ranges and advanced integrated circuit topics for CMOS and GaAs radio design, but these would not fit into an introductory text such as this one. Another item the book doesn't emphasize is the wide variety of online tools available now for RF designers. The website [...] has consolidated a number of links to free tools covering many aspects of RF design mentioned in this book, including a Pi Network calculator, S parameter utility and Smith chart Java tool.
In conclusion, this book is ideal for either the RF design hobbyist or professional digital designer who needs to design front end circuits without going back to school. The book has a companion website with high resolution versions of many of the Smith charts in the book, [...]
If Chris's book sounds too technical, you may want to start with Jon Hagen's "Radio Frequency Electronics" or if you are more into the magnetics side of it try Jerry Sevick's "Transmission Line Transformers". Lastly, if you need some general testing guidance, Joseph Carr's book "Practical Radio Frequency Test & Measurement" will likely be of some benefit.
Having worked with the industry leaders in this field, I can honestly say that Chris and his colleagues are among the best in the industry and Chris's experience shows in the content of this very fine work.
Eventhough the cover says "thouroughly revised" there are still a lot of typos like duplicated words, and a few mistakes in the solved excercises, nothing really serious though. However there's a reference to a data sheet in the first chapter that im still trying to find.
I would say that you need prior knowledge to really understand this book, like electric circuits theory, BJT and FET transistor operation, biasing and transistor configurations, transmission lines, modulation and types of modulation (AM, FM,QAM, PSK, etc..), also knowing Matlab and a bit of feedback theory wouldnt hurt.
Now I will try to give a very brief overview of each chapter, in my opinion, the meat of the book is in the first 6 chapters, the rest of the chapters are introductory at best, the last chapter on RF Design Tools is just out of my league. In general I felt that the book was a bit overcrowded with datasheets and tables as to "fill in" the space and make the book a bit thicker than it actually is, however its not just random data, since most of the time it is relevant to the subject in question.
Chapter 1: Gives you the basics, but in a more realistic manner, meaning that you study how real inductors, capacitors and resistors work, along with their parasitic effects, and behavior at different frequencies, in contrast to the approach you usually learn in an electric circuits book using ideal components. It also explains how to calculate and build your own inductors, it reminded me of the book "The circuit designers companion".
Page 19 makes a reference to some curves on a data sheet for a model BBR-7403 which im still trying to find (even online), if you know where to find it please let me know,
Chapter 2: The book talks about resonant circuits and how to take into account the non ideal properties of inductors, which serves as an introduction for circuits used through out the book.
Chapter 3: Covers filters, specifically passive filters, it starts using concepts from chapter 2 on resonant filters to develop simple 2nd order RLC filters, and ends up with multi order filters. It covers Butterworth, Chebyshev and Bessel filter design and characteristics.
The design approach to develop such filters is extremely straightforward, the mathematical derivations are kept to a bare minimum, instead, tables are provided for the reader in a "color by numbers" approach in which you follow a certain procedure to determine the order of the filter needed, and then you just look for the normalized component values on the table, making it extremely simple, however I believe it limits you only to the values presented on the tables.
The author explains how the Butterworth tables are obtained when both the source and load impedance are the same, but he doesnt explain how the tables for uneven load and source impedance are obtained, which kinda disappointed me, the same case happens with the Chebyshev and Bessel tables, in which its left to the reader to find out how the tables were obtained. In my opinion there should be an appendix with the Butterworth, Chebyshev and Bessel mathematical derivations to fill in the gaps for those of us how would like to do more than just crunching numbers, in order to make our own tables for exact load to source impedance ratios as needed.
Chapter 4: In my opinion this is the best chapter in the book, it covers impedance matching networks in depth, and provides you with several methods to calculate the correct answer using either analytical methods, or using the smith chart which is introduced in this chapter and used extensively in the rest of the book. It also provides matlab and other specialized software examples to calculate different parameters of matching networks.
Chapters 5 and 6: Cover Y and S parameters, Chapter 5 gives you an introduction to transistors and an in depth explanation on what are the Y and S parameters, using 2 port network theory, it helps you determine several parameters using transistor datasheet, as well as the smith chart. It also teaches you how to determine S parameters from Y parameters. Chapter 6 works on the design using Y and S parameters, including stability using the Linvill, Stern and Rollet stabilitty factors (no derivations are presented), finding the optimum bias point, and optimizing the circuit to obtain maximum gain or a specified gain by using the impedance matching networks presented on chapter 4, or to stabilize an unstable circuit by means of such matching networks.
These two chapers could be considered the most complex or math heavy chapters in the book, however no mathematical derivations are presented, but rather the final formulae. Again, the smith chart is the main tool to calculate the different parameters including stability circles. Everything is further explained by using the Matlab RF toolbox , and providing a design example at the end of chapter 6 using software tools.
It should be noted that the before mentioned chapters cover only small signal. Also, eventhough the material is very well presented, it only really tells you how to bias a certain transistor, and not how a real amplifier works as a whole and how the different stages interact with each other, it doesnt provide a real life circuit of say a low noise amplifier. I think there should be a schematic of a real amplifier with a brief explanation and what each of the stages do, although I understand that an entire book could be made just on amplifiers.
Chapter 7: This in my opinion is the poorest chapter in the entire book. It is 16 pages long, from which 4 are just datasheets. It barely covers amplification clases (A, B, C), but the author just mentions them. Theres actually no power amplifier desing, but rather power amplifier characteristics, no biasing or configurations are actually explained but rather a block diagram approach is used. Instead, it covers how to match power amplifiers to coaxial lines using a Balun and how Balun's are made. The automatic shutdown circuitry explanation is only one paragraph long.
I was very disappointed with this chapter, I understand that power amplification is a subject on its own, yet the title of the chapter is misleading, since no RF power amplifier design is actually covered, not even in the slightest way. The editor chose to advertise this chapter at the back of the book with stuff like "automatic shutdown circuitry" when the author barely mentions it in one paragraph, its misleading marketing.
Chapter 8: This chapter covers a modern approach on RF front ends. Explaining briefly how demodulation works, superheterodyne recievers, and the parts of a common RF front end, again, in a block diagram level rather than in a circuit level. It covers key concepts like 1db Compression, third order intercept point, noise factor, sensitivity, selectivity, etc.. This is a very informative chapter, yet again, everything is left in as a basic introduction of concepts,
Chapter 9: Presents different software tools and its application, it also comments on the real life stages of design of a product and what is covered in each stage in what the author refers to as the "design flow". PCB design, and and circuit simulation is covered in this chapter, aswell as the more industrial approach on product desing. It is a very interesting chapter and gives you a feel of how stuff is actually made, however most of the software and tools are just way out of my league since they are very expensive and tailored to RF professionals working in the field, yet if you are an RF professional, the information in this chapter is probably not enough.
Several screenshots and graphs are provided, yet they are really hard to appreciate. The authors provided a website with all the smith charts in color, however I dont know why they didnt provide the screenshots as well...
Overall I would say this is a great book, or a great introductory book to RF circuit design. I definitely enjoyed reading it and I learned a lot. One of the things I liked the most is that it is very straightforward yet it doesnt fall in the "cookbook" cathegory (with the exception of the Butterworth, Chebyshev and Bessel filter), so you do simple procedures, yet you get a good idea of whats going on. I love that modern software tools and techniques are incorporated into the book, and not just mentioned but actually explained.
Its not a book for a hardcore academic, its a good introductory book for engineers, its definitely not a book for beginners. It kinda reminded me of the book "The Art of Electronics" in a way that the information is presented in a very practical way, and some rules of thumb or know values are used to solve problems, yet, it is easier to follow than The Art of Electronics.
This book should be a must read for every engineer who wants to start a career in RF design.
Unfortunately, there are a number of words that are not used correctly in the book. It appears that they had a good spell checker but apparently did not have a good proof reader to review for grammar and meaning. There is at least one diagram that is in the wrong chapter and mislabelled. Overall I was pleased with the information provided.
