Electronics IV

Objectives

This course aims transmit to the students, knowledge in analysis and design of high frequency electronic circuits, with focus on radio frequency (RF) systems. The students, at the end of this course, should be capable to solve the problems associated to the project of RF circuits, and understand the basic techniques of project and implementation matching networks in printed circuit boards. The examples used are low noise amplifiers and oscillators.

 

The students will develop the skill to solve problems, work in a team and improve their capability to control the available time. Special attention is given to written and oral presentation of the work.
