Subject description
The course provides a theoretical foundation of high-frequency (HF) phenomena in electronics with an emphasis on practical design of HF circuits. Students first acquire basic concepts in the field of information transmission, noise, wave propagation, and antennas. This is followed by an overview of HF systems and concepts of frequency mixing and modulation. The main part of the subject then focuses on the propagation of HF signals in waveguides and transmission lines, HF phenomena in digital systems, and circuits with harmonic excitation, with particular emphasis on methods of analysis and design of HF circuits for the purpose of maximizing signal gain, minimizing noise, or maximizing output power. In this process, students become familiar with and master S and chain ABCD parameters, as well as the Smith chart, as indispensable tools for the analysis and design of HF signal paths, line tuning, and signal filtering with lumped and distributed elements.
The subject is taught in programs
