Course criteria & registration


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 they 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.


Selected high-frequency components, such as couplers, circulators, power dividers; Methods for circuit 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 oscillators and phase locked loop, Impact-Diode, Gunn-Element, microwave tubes (klystron, travelling wave tube, magnetron), noise, noise calculation, and noise matching, 2-port amplifiers and stability; Transmitter and receiver concepts; Design and analysis of circuits with computer aided design tools (CAD)


Mathematics, Signal representation, Electrodynamics, Circuits The successful participation in the following modules is recommended: - EI0609 Einführung in die Hochfrequenztechnik (Introduction to High-Frequency Engineering) - EI7003 Technische Felder und Wellen (Fields and Waves)


Examination is adapted to the learning outcomes and consists of a 90-minute written exam. In the written exam students demonstrate theoretical knowledge of components, amplifiers, and circuits. They answer questions under time pressure and with limited helping material (10 pages or 5 sheets of self-made documentation, mathematical formulary, non-programmable pocket calculator). They demonstrate understanding of relevant physical effects and design principles by solving analysis and design problems. During the semester, students may undertake project and design tasks, in which they solve various analysis and design problems in more detail. These project tasks can be used to improve the final grade. The final grade results from the written exam (100%). The overall grade for the project tasks will count 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.
