LEARNING OUTCOMES: the main purpose is to provide methods of analysis and design for high frequency components and circuits.
KNOWLEDGE AND UNDERSTANDING: the student should be able to understand and know the methods of analysis and design studied in the course.
APPLYING KNOWLEDGE AND UNDERSTANDING: the student should be able to apply the models of the studied components to the design of high-frequency circuits.
MAKING JUDGEMENTS: in the mathematical model of a component, the student should be able to find by himself the basic assumptions and the corresponding introduced physical approximations.
COMMUNICATION SKILLS: the student should be able to discuss the topics studied in the course with mathematical rigor and using the proper terms.
LEARNING SKILLS: if necessary, the student should be able to significantly and autonomously increase his knowledge of the topics analyzed in the course.
