Synopsis:

Goal of the lectures is to explain to students basic principals of rf. and microwave circuits, both passive and active (e.g. attenuators, couplers, isolators and circulators, modulators, oscillators, mixers and amplifiers). In conclusion to subjects on theory of EM fields a topics of transmission lines and waveguides (e.g. microstrip line, coplanar line, circular, , H and dielectric waveguide) and resonators (a section of transmission line, cavity, open, dielectric) are described Further a circuit analysis based on scattering parameters is being explained. Basic applications of rf. and microwave circuits are being discussed.
