This lecture is dedicated to the introduction of design methods for RF and microwave circuits for wireless applications. It introduces the concepts of transmission line and its application as distributed electronics. Matching techniques together with Smith chart as well as “S” matrix will be introduced and illustrated on worked examples. Then passive devices, such as resonators, couplers, and filters will be studied and developed on several examples. It follows active circuits such Low Noise Amplifiers and Power Amplifiers. Noise figure and Nonlinear parameters will be introduced. Frequency up-converter and down-converter will be described too. Then, integrated antenna constraints will be discussed. Finally link budget and noise figure of a wireless system will be discussed.
Lunedì 4 Aprile – Giovedì 7 Aprile (ore 9:00-13:00).
Totale ore: 16
