Module summary
In order to pass this module, students must obtain a mark of at least 30% in the final examination, as well as obtaining an overall mark of at least 40% for the module.Objectives
This module gives students an introduction to high frequency circuit analysis and design using both analytical and computer-based methods. In laboratory work, students are introduced to a range of high frequency test equipment in a variety of transmitter-receiver and transmission-line experiments. In lectures, students learn the fundamentals of high frequency circuit techniques and electromagnetic analysis.Learning outcomes
On completion of this module, students should be able to:
- apply basic physical and mathematical principles to transmission line problems in terms of reflection coefficient and impedance transformation;
- apply circuit theory and modelling techniques to the design and analysis of high frequency filters, matching networks and amplifiers;
- use quantitative methods and software tools to the analysis and design of high frequency electronic circuits;
- apply a systems approach to the analysis and design of radio communications systems, including breaking a system down into constituent blocks and understanding the interface between them;
- demonstrate familiarity with high frequency electronic components, such as microstrip circuits, and related measurement equipment;
- demonstrate good laboratory skills, including the safety aspects of lab work, keeping a log-book and writing up laboratory work;
- demonstrate a qualitative understanding of electromagnetic fields and waves and the ability to apply mathematical analysis to a range of static problems including the coaxial line.
