After successful completion of the course, students are able to use and understand scattering parameters (S-parameters), use the Smith-chart to solve linear RF-problems, and understand basic RF-elements like attenuators, directional couplers, hybrids, circulators. Students will learn how to design matching networks for optimizing gain or noise figurre and unerstand the basic concepts of RF power amplifiers and their distinguation from small signal amplifiers. In the field of RF system design, students will be able to analyze the signal to noise ratio (SNR) of an entire RF receiver by level-planning, know the effects of nonlinearities (intermodulation), understand concepts of homodyne (direct conversion) and heterodyne receivers. Furthermore, students will learn the basics of analog/digital modulation formats and parameters to characterize modulation quality. Also, students will get a general understand of phase locked loop synthesizers and the effect of phase noise.

The lecture is split into:
- Oral presentation (~20 units)
- Exercises (6 units): before each exercise, students can (optionally) hand in solved problems which will be discussed during the exercise. Besides the ongoing training, correctly solved examples give you a better grading of written/oral exam
If the number of available lecture days allows for it, the lectures include as well:
- Live-demo with a spectrum analyzer to analyze the electromagnetic spectrums and/or devices brought by students
- Q&A session as preparation for the written exam
All lectures are without mandatory attendance.
Administrative Meeting (together with first lecture)
Administrative issues concerning the lecture will be discussed in the first lecture on October 1, 2024, 9:15 AM.
Please note that also the lectures will start always at 9:15 AM.

Grading is based 20% on multiple-choice tests and 80% on a written+oral exam.
- Multiple-choice tests: Four multiple choice tests (during the lecture, dates will be announced in the administrative lecture) will give you up to 4 x 10pts = 40pts.
Grading scale: 1 (≥ 30pts), 2 (≥ 25pts), 3 (≥ 20pts), 4 (≥ 15pts). Note: attending two tests already allows you a positive grading on this part.
- Combined written+oral exam: The written exam has 4 problems with 100pts in total. A minimum of 20pts each are needed for the part "linear systems" and "nonlinear systems". Copies of the lecture notes will be provided (you are not allowed to bring your own) during the 3h exam. After a positively graded written exam, the understanding of the theory will be checked in an oral exam
Grading scale written exam: 1 (≥ 90pts), 2 (≥ 75pts), 3 (≥ 55pts), 4 (≥ 40pts). The total grade for the written+oral exam is not the average of both parts. Instead, the written exam's result sets a baseline that can be improved/worsened based on the oral exam performance. Finally, solved problems from the exercises can improve your total written+oral grade by up to one grade.
In case of the oral exam is not passed, the written exam's result can be counted for future oral attempts.
