Recommended, as written
Knowledge of topics of physics and electrical engineering at a level corresponding to the first four semesters of a Bachelor’s degree in electrical engineering or corresponding to the level of a Bachelor’s degree in physics
Contents
1. Waves on lines • transmission-line equivalent circuit, line parameters • Coaxial cables and waveguides: modes, dispersion, losses 2. Reflection and Smith chart • Reflection coefficient, impedance transformation, standing waves • Smith chart • Matching circuits • Resonators, quality factor, bandwidth 3. S-parameters • Linear multi-ports, S-parameters • Mason graphs, Gain definitions, stability • Lossless multi-ports 4. Couplers and dividers • Couplers • Dividers, Wilkinson divider 5. Noise • Mathematical fundamentals • Physical noise sources • Noise figure, cascaded two-port networks • Noise parameters 6. Semiconductor devices • Diodes • Field effect transistors • Bipolar transistors
Learning outcomes
The students know the basics of radio frequency techniques. They are familiar with the propagation of waves on transmission lines and resulting effects like reflections. They are able to calculate linear mulitports based on scattering parameters and know how to obtain matching. They know common active and passive RF devices.
Assessment
Prerequisite: • Successful completion of exercises (solving of the exercises and submission of a written solution to the exercise date) Final module examination: • Written examination, 120 min.
