Every wireless device that surrounds us, from the phone in a pocket to the radar in a car bumper and the satellite link that carries a television channel, depends on a body of knowledge that engineers call radio-frequency (RF) engineering. At these frequencies the comfortable rules of low-frequency circuit theory begin to fail: a length of copper is no longer a simple wire, a capacitor becomes an inductor above its self-resonant frequency, and the layout of a printed circuit board becomes as important as the schematic drawn on it. This book was written to guide the reader through that transition in a way that is rigorous, practical, and, I hope, enjoyable.The text grew out of many years of teaching RF and microwave courses to undergraduate and postgraduate students, and of supervising laboratory projects in which students designed, built, and measured real circuits. The recurring lesson from that experience is that RF engineering is learned best when theory, design procedure, simulation, and measurement are kept side by side. Accordingly, each chapter develops the physical ideas first, derives the essential equations carefully, and then converts the equations into step-by-step design methods that are illustrated with fully worked numerical examples.The seventeen chapters follow a natural path. Chapters 1 to 3 build the foundations: the RF spectrum, the decibel, skin effect, transmission-line theory, and the Smith chart. Chapters 4 to 6 treat impedance matching, network parameters and scattering parameters, and the planar transmission lines and waveguides on which practical circuits are built. Chapters 7 to 9 cover passive components, resonators, power dividers, couplers, and filters. Chapters 10 to 13 move to active circuits: small-signal amplifiers and stability, noise and low-noise amplifiers, power amplifiers and nonlinearity, and finally mixers, oscillators, and frequency synthesizers. Chapters 14 and 15 widen the view to antennas, radio propagation, transceiver architectures, link budgets, and RF measurement techniques. Chapter 16 turns to the practical craft of RF hardware: circuit-board stack-ups, layout parasitics, decoupling, shielding, electromagnetic compatibility, and bring-up, and Chapter 17 applies the ideas of the whole book to radar and RF sensing systems, from the radar range equation to 77 GHz FMCW automotive radar. Four appendices collect useful constants and formulas, suggest further reading, provide a compact Python toolbox that implements the principal design equations of the book, and review the mathematical tools used throughout.Several features have been included to make the book useful both in the classroom and on the bench. Learning objectives open every chapter, and key-point boxes highlight ideas that are easy to forget. Worked examples show complete numerical solutions with realistic component values. Short Python programs demonstrate how the design equations are implemented in code, so that the reader can experiment with parameters and see the consequences immediately. Each chapter ends with a summary, a hands-on design project, and a set of problems ranging from routine exercises to open-ended design tasks.The reader is assumed to be familiar with basic circuit analysis, complex numbers, phasors, and elementary electromagnetics. No prior exposure to RF design is required. Mathematical developments are kept as transparent as possible; whenever a result is quoted rather than derived, the reason and the conditions of validity are stated.
