I am the CTO of an organization specializing in electromagnetism, EMI / EMC, filter design, and power electronics. I purchased this book to ramp up one of our design teams on a large, recently initiated RF design project. This book provides an excellent introduction to the both the theoretical and practical aspects of radio-frequency design and testing. All of the subjects are presented clearly and concisely. I have recommended the book to our top-engineers and plan to buy multiple copies. I own 60-100 reference texts covering a wide array of electrical and mechanical engineering subjects, including several on radio frequency design: this is one of the best reference texts, on any subject, that I have read.
