Learning Outcomes |
Competences |
Students know the most important RF components such as amplifier, mixer, filter, antenna, signal source, as well as RF measuring devices such as spectrum analyzers and network analyzers and can use them to carry out practical measurements.
Students can analyze cascaded RF systems in terms of basic properties (gain, noise) and practically implement a wireless 10-GHz audio transmission in the laboratory and describe the necessary components including antenna and radio link. Statistical performance of a frequency measurement can be predicted by using the Cramer-Rao-Lower-Bound (CRLB).
