Type: Compulsory
ECTS Credits: 6.0 ECTS


Requirements (Subjects that are assumed to be known)
Linear Networks analysis and synthesis, Electromagnetic Field Theory
During this course the student will learn all the basic concepts on microwave circuits. In order to do that, the student will acquire knowledges in these areas: - Analysis and design of passive devices and introduction to active microwave circuits. - Study of the tools for the analysis and design of microwave circuits: Smith chart, S parameters. - Analysis and design of passive microwave circuits: matching networks, power dividers, directional couplers, resonators and filters and non-reciprocal devices. - Introduction to active circuits Concerning skills, these can be generic or specific: Specific skills: - Review of the guided-wave propagation fundamental topics (taken from the course in Electromagnetic Field Theory) and transmission line theory. - Knowledge of circuit theory to analyze microwave circuits: o Knowledge of transmission line as a circuit: Smith chart. o N-port network analysis: scattering (S-) parameters. - Skills for the design of passive microwave circuits: o 2, 3 and 4-port networks: power dividers, combiners and directional couplers. o Resonator analysis o Analysis and design of microwave filters. o Introduction to passive non-reciprocal circuits. - Introduction to microwave measurements: impedance measurement and network analyzers. -Introduction to microwave amplifiers. Generic skills: - Understanding the roll that RF front-ends have in a communication system. The student will be able to apply his mathematics and physics knowledges to design circuits for transmitting or receiving communication signals. - The student will be able to identify the necessary circuits for designing an RF front-end with simulation tools (AWR or ADS software) and measure the corresponding prototypes (networks analyzer). - The student will be able to work in group and present the results of their work in an effective way. - The student will understand the need of developing a continuous learning in order to update all the technological advances.

Learning activities and methodology
The teaching methodology will consist of three parts: * Lectures on the main theoretical topics: the main theoretical topics of the course will be presented in these classes. Both the blackboard and computer presentations will be used. The students can have a text book and a set of slides covering all the topics in the course. This set of slides will be available from the beginning of the course. * Lectures on practical exercises. The students group will be divided in smaller groups with less than forty students. The students can have a problems book with many problems covering the topics of the course. * Practical work in the laboratory. The students will be divided in groups of 20 students to realize the four proposed practical works (in 6 sessions). They will work in groups of 2-3 students. In all the session a final quiz will have to be filled by the students. * Tutorship: There will be up to four time slots for tutorship during the week. These slots can be used by students once they have applied for it by e-mail. In addition there will be other collective tutorship. Students are encouraged to make use of both teaching mechanisms.
