Abstract :
Electronic circuits and systems are working at frequencies that rise at an accelerated pace. For instance, one can observe the sustained rise of the clock frequencies of computers and digital circuits. Consequently it becomes obvious nowadays that an electronic engineer should acquire some basic expertise in High Frequency techniques. The main objective of this course is to fulfil this need by presenting the various basic knowledge and techniques that are useful for designing High frequency circuits and systems (mainly, radio communications systems). From a pedagogic point of view, this course brings some complementary information to the courses: Mixed Electronic and RF circuits (UVE4Ba). Moreover, it constitutes a theoretical basis for the electronic design projects of S3 and S4 and a recommended prerequisite for attending the various courses that are proposed in S5 in the field of analogue electronic. (Particularly the projects of RF circuits design).
Plan :
    • RF units.
    • Quality factor Q, general definition and RF applications.
    • Power matching strategies.
    • Noise, noise matching.
    • Impedance matching with lumped elements:
    • Matching with analytical methods
    • Matching with analytical methods (Smith chart)
    • Matching with the help of CAE/CAD software tools (Smith Tool / Ansoft Designer)
    • From the concept of power matching to the principle of S parameter of a dipole
    • Extension to the Sij parameters of a quadripole
    • Theoretical network analysis with Sij parameters
    • Application of the Sij parameters to the design of oscillators; relation with the negative resistance method.
    • Graphical network analysis with the flow graph and Sij parameters.
    • Application of the Sij parameters to the design of linear amplifiers.
    • Extension conditions of the Sij parameters to non linear power devices.
    • Sij parameters measurement, the calibration issue.
    • Practical work/Project : Design of the matching networks of a linear amplifier with the aid of Ansoft Designer’s Smith Tool.
