Formation/Cours

The knowledege of the basics of the transmission lines theory in sinusoidal regime is required :
– characteristic impedance of a transmission line, wave velocity
– forward and reflected waves, reflection coefficient, standing wave ratio
– voltage, current and impedance on a transmission line
– SLUG, STUB
– Impedance and reflection coefficient relationship on the Smith chart

These prerequisites can be found in a lecture like : Wireless Technology and applications ( 0910-ISEN-M1P1-ST-MB-502 )

The goals of the lecture is to introduce the concepts, the techniques and the tools to design and realize electronic circuits at microwave frequencies such as amplifiers. In particular, the lecture explains the techniques of impedance matching between circuit stages. A second part of the course is focused on the concept of the S parameters that characterize electronic devices at microwave frequencies.

– Smith chart
– Impedance matching networks using lumped elements and distributed elements
– Microstrip lines and circuit board design
– S parameters concept
– Microwave amplifier design : gain, stability, noise
– CAD (ADS software)
