| Module Overview |
| The module will introduce the design and analysis of some of the key circuits used in modern RF electronics. An introduction to RF antenna theory and design will be given, and this topic will be extended to consider the behaviour of propagating wireless signals at RF frequencies. As an example of an RF communication system, the module will cover the basic principles of pulsed and CW radar. |

|
| Module Aims |
To provide familiarisation with RF Electronic design to encourage the production of RF engineers for industry.
|
|
|
| Learning Outcomes |
Students will understand the essential principles of RF circuits and communication techniques. They will be able to analyse and design basic RF circuits and perform essential RF system calculations. |
