Smith Chart — Lesson 4

This lesson covers the concept of Smith Chart and its applications. It delves into the transformation of incidences to reflection coefficients and the conversion of straight lines to circles in the Smith Chart. The lesson also explains the implications of lump element inductors and capacitance in microwave circuits. It further discusses the concept of bilinear transformation and the difference between red and white mixtures in the Smith Chart. The lesson concludes with an application of Smith Chart in finding the Voltage Standing Wave Ratio (VSWR) of a load.
