The course is taught in English. The course illustrates the principles of operation, and provides the design criteria of the main passive components used in microwave and millimeter-wave systems. The course also provides an introduction to electromagnetic compatibility, with particular emphasis on signal integrity, conducted and radiated interference, and mitigation of interference due to electromagnetic fields in electronic devices.

- Capability to represent multi-port devices with equivalent matrices and to relate the properties of the latter to the physical characteristics of the component they represent. - Knowledge of the operation principles of the main microwave an millimeter-wave passive components. - Capability to design microwave components in microstrip technology. - Capability to use simulation tools for microwave components. - Capability to measure microstrip components. - Knowledge and ability to model noise and interferences on transmission lines. - Knowledge of basics of emissions and susceptibility of components and systems, and of the techniques for their suppression.

- Basics of guided electromagnetic wave propagation: transmission lines. - Basics of electromagnetic wave propagation in free space.

Conventional transmission line review, introduction of Multiconductor transmission Lines and of S-parameters for the representation of N-port devices (1 CFU) Microwave components, their characterization and design techniques, and their use in microwave systems. (4 CFU) Signal integrity: distortions due to mis-matching, cross-talk. (1 CFU) Rediated field review, introduction of radiated emissions and susceptibility. (1 CFU) Numerical and experimental characterization of the considered devices, EMC measurements (1 CFU)

Problem-solving classes integrated with lectures. Exercises assigned almost weekly, to be held mainly at home (homework). They are solved during the exercise classes, the week after the assignment. Experimental labs: measurement of microwave components and radiated emissions. The measures will be taken by students divided into teams and assisted by experienced staff. Numerical labs on the simulation of microwave components in the MATLAB envirnment and with commercial software, assisted by experienced staff. Group activity (optional) devoted to the design of one of the components analyzed during the course, to the simulation of its behavior and to the measurement of a prototype, that will be manufactured by experienced personnel.

Modalità di esame: Prova orale obbligatoria;

The main aim of the exam is to verify the learning level of the course topics, i.e. the capability to design the passive components that are commonly present in the RF block of an electronic circuits, to perform their critical analysis, to quantify the effects of interferences and to find possible solutions for their reduction. The exam consists in an oral test organized as in the following. - The first part lasts 30 minutes and has the aim to verify the acquisition of the course competences (see expected learning outcomes) through the solution (at least partially) of a couple of problems similar to those solved during exercise classes or proposed in the weekly assignments. Students need only to take with them what is necessary to write and the calculator. No books, solved exercises or notes are allowed. The useful formulas are directly added into the problem text. - The second part is a discussion of the solution of the problems handle in the first part. The maximum achievable grade of the oral exam is 26/30. If it is at least equal to 18/30, it is possible to improve the final grade up to 30/30 cum laude with the following activities, that are not mutually exclusive. - The submission of the assigned exercises (homework); their aim is to help the students to deal with the different subject matters immediately after their explanation, to have the possibility of asking clarifications without waiting for the end of the course. - The submission of short reports on the lab activities. - The submission of a short report on the optional project activity. It will consist in the design, numerical characterization and measurements of one of the devices considered during the course (e.g. a filter). The course instructors are responsible for its manufacturing. The activity is carried on in small groups (2-4 people) or exceptionally also by a single student. One report for each group is required, to be delivered before the end of July's exam period. The aim of this activity is to teach students to face a "real problem", learning to use a commercial tool for the numerical analysis of the component, and to discuss the effects of manufacturing tolerances and the possible discrepancies between computed and measured results. A maximum of 6 marks can be gained with these three activities.
