CHAPTER 1 - Fundamentals of Electrical Circuits 2 After the conceptual and practical treatment of transmission lines, the maths which is used to design, model and analyse such elements is illustrated. This leads to the mathematical definition of reflection coefficient and impedance seen for a single-port network and then extends to the definition of network parameters for two-port networks. Graphical tools for impedance representation based on such parameters are then introduced (Smith Chart). The basic concepts of impedance at high frequency are then revisited and enhanced to include series and parallel passive networks comprising of both resistive and reactive elements. The basics of impedance matching are then explained on a conceptual basis and some basic examples are illustrated which describe L-section matching and series to parallel conversions. The simplification of impedance matching through the use of Impedance and Admittance Smith charts is then illustrated and a number of video tutorials based on simulations are made available to the reader. Finally the basic techniques for high frequency amplifier design are illustrated and a number of video tutorials are provided to corroborate the students' learning. I firmly believe that Radio Frequency and Microwave Engineering is not a game of Sudoku where you just apply rules to get the result that you want. To really be a successful designer you must understand the concepts not just the procedures behind high frequency circuits. In particular, an understanding of what happens in the time domain and what an impedance represent is truly crucial when working with advanced amplifier topologies such as Doherty and when trying to model devices and systems. It is highly recommended that the reader who is not familiar with the AWR Microwave Office simulation software watches the introductory video (video 1.1) before any of the others.
