Description
The term "impedance matching" is rather straightforward. It's simply defined as the process of making one impedance look like another. Frequently, it becomes necessary to match a load impedance to the source or internal impedance of a driving source. A wide variety of components and circuits can be used for impedance matching. In this course, with the help of Smith Software from Prof. Fritz Dellsperger (at Bern University of Applied Sciences), we will explain how to match the impedance by using RLC elements, Transmission like, open/short stub to any wanted value. This course is suitable for every Engineer who wants to work as RF/Hardware Engineer. Smith Software contains Smith Chart, which facilate the process for impedance matching for us. Smith chart contains below capabilities in the software.
