ELT-41727 Practical RF Electronics: First Principles Applied, 5 cr


This course is an introduction to radio frequency design. It shows how the most fundamental building blocks of RF electronics can easily be understood, constructed, and tested in practice. We also review mathematical tools needed therein.

This course is composed of in-class and out-of-class tasks that provide elementary understanding that is the basis of all RF design. In most tasks students work in small teams and build basic RF circuits on solderless breadboard and test their operation. These building blocks evolve gradually from simple blocks such as a transistor amplifier into oscillators, modulators, mixers, and complete transmitters. Hands-on tasks include also antennas, filters, and demodulators.

Students get on loan a 'mini-lab' that comprises (1) electronic components; namely transistors, resistors, capacitors, and inductors; (2) a solderless breadboard; and (3) a myDAQ that is a small-size USB-device that operates, for instance, as an oscilloscope, signal generator, and digital multimeter. With the 'mini-lab' students are able to rehearse with the ideas and concepts that are applied in construction of a simple but fully functional 18-MHz radio transmitter.
