AWR eBooks

XI It is important for Universities to realise however, that computer simulation of an electronic design is not the end-point, but only a step in the realisation of the production of hardware that operates as required. That is why in this book, firstly computer simulation has been used to enhance the understanding by students and designers of the properties and limitations of their designs, and secondly many photographs and measured performance of the hardware realisation of these designs presented have been included. I hope that the material presented in this book will increase the RF and microwave design skills of many students and practicing designers. This whole book is suitable for teaching RF and microwave electronic design in the final year of an undergraduate Bachelor Degree program or as a course in a postgraduate program. Chapter 2 can be used at earlier years of a Bachelor Degree program to teach the principles of computer simulation, the design of analogue electronic circuits and passive circuit analysis. These computer simulation techniques are not limited to RF and Microwave frequencies. For that reason, chapter 2 includes examples operating below 100 kHz. The modelling of mains (50/60 Hz) power distribution transformers, described in chapter 2, could not have been done without the optimisation capability of AWR DE. Unless otherwise indicated, any of the hardware shown in photographs, have been designed by the author and produced by him with assistance from JCU and technical staff. There are some photos of hardware from unknown manufacturers (UM). Those have been labelled with (UM). This fourth (2022) edition includes new material on couplers, mixers and advances in 3D printing of PCB's and Device models, as well as many other updates, such as changing examples to use currently available devices. A new appendix on plotting using AWR DE is also included. As a result, this edition is 66 pages larger than the 2018 edition. This fourth edition used AWR DE V16 project files; as a result, many figures have been updated to reflect the slight changes in appearance from earlier versions. Acknowledgment I thank my wife Maxine for her patience and tolerance of my absences over many years, as I fulfil my desire to teach students the art of electronic design, being absorbed in research in the design of instrumentation and communication equipment. I thank her for being able to spend a lot of my time in writing and updating this book and the accompanying project files, even in my "retirement". I thank my colleagues at James Cook University, for their encouragement and feedback on the course that resulted in this book. I thank AWR for making their software available for teaching at James Cook University. Without that, this book could not have been written. I thank Dane Collins and Sherry Hess from AWRCorp, for the novel step that we took in distributing this book on their web site. That allows this book to be used by many more students. I thank the late Prof Mike Heimlich, from Macquarie University, who peer reviewed the first edition of this book and made many very valuable comments. I thank the AWR support staff, for helping me when I could not get some of the project files to work correctly. I thank Cadence and their staff; David Vye, for firstly providing project files for modelling amplifier performance and secondly, together with David Junkin and Kira Jones continuing the vision of making this book readily available to university staff and students around the world. Finally, I thank Prof. Mohan Jacob from James Cook University, and Dr. Sudipta Chakraborty from Macquarie University who both peer reviewed this edition of the book. Their comments have been incredibly valuable and resulted in this book being much better than the draft version. RF Electronics: Design and Simulation XI www.cadence.com/go/awr
