Objective of the course:

At the end of the course the student must be able to:

  • Develop skills in analysis and design of RF circuits
  • Identify the current relevance of RF and Microwave techniques in modern electronics circuit design
  • Design fundamental RF circuits such as impedance matching networks, filters, amplifiers and oscillators
  • Analyze physical interconnect networks implemented in typical planar technologies (microstrips, striplines, etc)
  • Understand the trade-offs in circuit architectures and how they translate to RF systems parameters (e.g. noise figure, IIP3, phase noise, etc)
  • Use simple back-of-the-envelope calculations to predict RF circuits’ performance
