# High Performance Electronics – (block B)

Educational objectives

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.

Prerequisites

The analysis methods of the lumped element networks. The most common devices and circuits used in the low frequency analogue electronics. The theory of transmission lines.
