Lehrinhalte
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.
