Design of High-Frequency Circuits

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. 

Understanding the theory of phenomena and operation of specific elements in high-frequency (HF) circuits. Utilizing dedicated analytical and graphical tools, as well as software, for analysis and synthesis of HF circuits and systems. Employing measurement methods and specialized instruments for characterization and optimization of HF circuits and systems. 

Lectures and laboratory exercises, that consist of solving theoretical problems and practical use of CAD tools for designing HF circuits.
