This subject deals with the analysis and understanding of the fundamental role of high frequency circuits (RF, microwave) and their associated techniques. The student will apply their mathematical and physical knowledge to the analysis and design of circuits for the transmission and reception of communications signals. In addition, they will be able to identify the circuits necessary for the development of a high frequency front-end by means of circuit simulation and the measurement of prototypes.
In particular, the objectives are the following:
1) To review the basic concepts of guided propagation explained in the subject Electromagnetic Fields: basic concepts of wave guides and transmission lines with an emphasis on their practical use.
2) To learn the use of circuit tools for the analysis of microwave circuits:
-Knowledge of transmission line theory from a circuit theory point of view: Smith's chart.
-Tools for the analysis of microwave networks: dispersion parameters (S).
3) To study the fundamentals and techniques used in the design of passive microwave circuits applied to:
-The networks of two, three and four ports: dividers, combiners and directional couplers.
-Passive non-reciprocal circuits.
-Lumped and distributed resonators.
-Microwave filters.
4) To study the problem of the analysis and design of microwave amplifiers.
5) To study the fundamentals of microwave measurements: impedance measurements and fundamentals of network analyzers.
