ELEC4604 - RF Circuit Design - Theory and Applications

Last modified by Leon Luo on 2023/02/24 01:58


This course focuses on the hardware aspects of wireless systems from a radio frequency perspective, introducing students to various RF building blocks present in communication transceiver systems. It covers topics such as passive and active RF components, RF device models, transmission line principles, Smith charts, matrix representation of RF circuits, multiport RF networks, planar technologies, lumped and distributed circuits, microstrip circuits, RF resonators, RF filters, RF amplifiers, and antennas. The course aims to provide students with a strong understanding of RF fundamentals for both the design and analysis of RF devices, and assumes a prior knowledge of electromagnetic theory ( ELEC3115 - Electromagnetic Engineering ) and circuit theory techniques ( ELEC3106 - Electronics ). By the end of the course, students should be able to analyze, design, and implement RF circuits.


These concepts are studied through course content, mainly lecture notes and course recommended textbooks. Please note, unless referenced from another source, please assume the following information presented is interpreted, studied, and re-expressed from the course content. Furthermore, please refer to the course content directly, e.g. ask the lecturer or read the textbook, for the most relevant knowledge required for the course.

Electromagnetism Review

As the course focuses on radio frequency content which stems from electromagnetism, it is highly recommended that you review ELEC3115 - Electromagnetic Engineering.

Transmission Line Theory

Lumped Elements vs Distributed Elements

It should be noted to students that in most analysis of electronics at the university so far is analysed in the perspective of low-frequency signals. In those conditions, elements such as resistors, inductors, and capacitors can be lumped as a single element. However, as the frequency of the signals increases, it is commonly accepted that.
