Entry knowledge

The student should be able to:
- explain basics of electronic circuits and electromagnetic waves and transmission lines (inductance, capacitance, impedance, reflection coefficient, Smith chart, standing wave ratio)
- analyze basic electronic circuits with passive components
- calculate with complex numbers and logarithms
- know the characteristics of the parallel and serial resonant circuits
- know classical classes of amplifiers and calculate operating point circuits

Rules for evaluation and completion of the course

Students obtain max. 30 points for the activity in labs during the semester. The final exam is composed of written and oral part for max. 70 points.

Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course annually.

Aims

The aim of the course is to get students acquainted with the theory of analysis and synthesis of the modern radio-frequency transceivers.
Student will be able: (a) to design common radio frequency circuits in modern transceivers; (b) perform numerical calculations for given specifications and computer simulation for functionality verification.
