Textbook in PDF format This textbook clearly conveys the fundamentals of RF technology and provides specific descriptions for designing linear components from parts and transmission lines for high-speed and RF circuits. It teaches readers how to model components, synthesize circuits, and optimize them. With the help of freely available simulation software, GHz circuits can be developed independently. Numerous practice examples allow for self-assessment of knowledge. Additionally, the functionalities of complex nonlinear components such as RF mixers, oscillators, and synthesis generators are presented
