Prerequisites

It is necessary to have succeed in the subject "Radiació i ones guiades"

Objectives

The objective of the subject is to provide the fundamentals for the analysis and design of communication components and circuits based on distributed parameters, i.e., transmission lines and stubs. To this end, it will be necessary to study the propagation in transmission lines and their fundamental parameters, including also the Smith chart as a tool for the analysis and design of circuits based on distributed parameters. It will be also necessary to study the microwave networks, the scattering matrix and their properties, as well as symmetry properties of microwave networks. The specific aim of the subject is that the student be able to design components and circuits subjected to specifications. Commercial simulation tools available in the laboratory will be used.

Learning outcomes

  1. Select specialized electronic circuits and devices for transmission, routing and terminals in both fixed and mobile environments.
  2. Design RF and microwave circuits
  3. Develop the capacity for analysis and synthesis.
  4. Develop scientific thinking.
  5. Develop systemic thinking.
  6. Work autonomously.
  7. Develop independent learning strategies.
  8. Prevent and solve problems.
  9. Make one's own decisions.
  10. Critically evaluate the work done.
  11. Work cooperatively.
  12. Communicate efficiently, orally and in writing, knowledge, results and skills, both professionally and to non-expert audiences.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Evaluation of the lab reports 25% 0 0 1, 2
partial and final exams 75% 0 0 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

Individual and continuous evaluation of the part “partial and final exams”, with at least two partial exams, will be carried out. If the continuous evaluation is not surpassed, the final exam will be mandatory. At least a score of 4 out of 10 is necessary in the final exam in order to surpass the subject averaging with the lab evaluation part. The average of the partial exams should be at last 4 out of 10 in order to avoid the realization of the final exam. This part has a weight of 75%. The results of the lab will have a weight of 25%. Lab is evaluated through an exam (weight 60%) and an inteemediate report (weight 40%).

To recover the activities (if it is necessary), it will be done after the lectures period. The score of the lab part cannot be recovered. The professors have the right to modify the evaluation procedure depending on the specific circumstances that may appear during the training period.

If a student do not pass due to not surpassing the minimum score in any of the evaluation activities, see above, the final score will be the resulting one, if it is less than 5, or 4.8, if the average score is above 5

Students that repeat the subject will maintain the score of the lab.

Copying or allowing copying will be penalized with a zero score in the corresponding activity.

If the student realizes a partial exam, he/she is evaluated with a score. This subjet does not consider \"unique evaluation\".
