Module Number: EI70410
Duration: 1 Semester
Occurence: Summer semester
Number of ECTS: 6
Professor in charge: Thomas Eibert
Study hours: 75
Self-studying hours: 105
The examination is adapted to the learning outcomes and consists of a written examination of 90 min duration.In the written examination, students demonstrate by answering questions under time pressure and with limiited helping material (10 pages or 5 sheets of self-generated documentation, mathematical equation book, non-programmable pocket calculator) the theoretical knowledge of components, amplifiers, and circuits. By solving analysis and design problems, they demononstrate the understanding of relevant physical effects and design principles.During the semester, students get the opportunity to participate in voluntary project and design tasks, in which they can solve different analysis and design problems in more detail. These project tasks can be used to improve the final grade.
The final grade consists of the grade of the written exam (100%).
The overal grade for the project tasks will count with 20% of the final grade, if the average grade of the written exam (80%) and of the project task grade (20%) will lead to an improvement of the grade.
Exam type: written
Exam duration: 90 min.
Possibility of re-taking: In the next semester: Yes At the end of the semester: No
Written paper: No
Mathematics, Signal representation, Elektrodynamics, Circuits
The successful participation in the following modules is recommended:
- Einführung in die Hochfrequenztechnik
- Technische Felder und Wellen
Selected high-frequency components such as couplers, circulators, power dividers; Methods for cicuit analysis, as e.g. scattering/transmission parameters, even/odd analysis, and signal flow graphs;Active devices, basic amplifier circuits, basic oscillator circuits, 1-port amplifiers, mixers and parametric effects, frequency multipliers and deviders, 1-port osicillators and phase locked loop, Impatt-diode, Gunn-element, microwave tubes (klystron, travelling wave tube, magnetron), noise, noise calculation, and noise matching, 2-port amplifiers and stabiliy;
Transmitter and receiver concepts
Design and analysis of circuits with computer aided design tools (CAD)
At the end of the module students are able to understand circuits for high-frequency amplifiers and oscillators together with their sub-components. Also, they are able to design such circuits themselves. The students know the physical effects, which are relevant for the functioning of these circuits. Also, they know passive components such as transmission lines, couplers and circulators and the know how to utilize such components for the design of oscillators and amplifiers. They understand the nonlinear effects which are the basis for mixers, mulitpliers, and parametric amplifiers.
In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in excercises and tutorials.
During the lectures students are instructed in a teacher-centered style. The tutorials are held in a student-centered style.
Additional project tasks for analysis and design of cicuits give the students the opportunity to apply their knowledge acquired during the lecture and the tutorials and to further deepen the understanding of the taught materials.
The following types of media will be used and also made available online:
- lecture notes
- tutorial problems
- project tasks for analysis and design of amplifiers and oscillators
