Objectives and competences

Understanding and the specific RF elements, RF circuits and RF systems usage and specific methods of analysis, synthesis, and design using CAD tools. In addition, the students will be able to analyze and use the basic HF circuits and systems characteristics and the basic concepts of Electromagnetic compatibility. 

Learning and teaching methods

Lectures and laboratory work composed of two parts: the use of CAD tools for design of RF circuits.
