Digital Teaching:
The lectures and exercises will take place online in the winter semester 2021/22.
The slides accompanying the lecture, exercises and video recordings will be available for download in the Moodle course for the lecture. Since Moodle is linked to TUCaN, enrollment takes place automatically.
Course Contents:
Part 1 Passive microwave components:
* Calculation of the two-port parameters of simple passive components and circuits (transmission lines and lumped elements) for MMICs
* Wave parameters and S-parameters
* Smith chart and matching circuits with line elements or lumped elements
* Design and equivalent circuits of passive microwave components (transmission lines, capacitors, inductors and resistors)
Part 2 Active microwave components:
* Design and equivalent circuits of field effect transistors (FET) and heterostructure transistors (HEMTs)
* Gain and cut-off frequencies
* Schottky contacts: function and characteristics
Part 3 Active microwave circuits (main part):
* FET amplifiers: operation, equivalent circuit, gain, matching circuit, stability and circuit implementation
* Oscillator design
* Mixer design
* Material choice (compound semiconductor material systems: properties, fabrication and requirements)
Applications of these circuits range from communication systems such as cell phones to satellite transceivers as well as high-frequency sources up to Terahertz.
Literature:
Script and slides will be handed out. Literature will be recommended in the lecture.
Preconditions:
Desirable: Introduction to Electrodynamics, Microwave Engineering I
Additional Information:
The requirements regarding the final exam as well as a test exam can be found in Moodle.
