Smith Charts: Designing a Series Stub Match with a Shorted Stub (00h6)

This is the first of the application videos in the Smith Chart series. In this video I will use a pencil and paper exercise to create a Series Stub Match with a Shorted stub. I will explain how they work, how they are constructed and how they are designed with a few practical hints along the way. 00:05 Introduction 01:15 What is a Stub Match? 04:22 What is a Series Stub Match? 05:41 STEP 1 = Measure the actual Impedance 06:11 STEP 2 = Know Your Coax (Measuring the Velocity Factor) 08:20 All the Facts in One Place - What are we working with? 08:58 STEP 3 = Normalize your measured Impedance 09:32 STEP 4 = Plot the Normalized Impedance on the Smith Chart & draw the SWR circle 13:13 STEP 5 = Move to the R = 1.0 Circle & read Impedance(a) here and lambda(a) 15:51 STEP 6 = Calculate coax length from Load to Stub (Impedance Transforming) 16:13 Calculate Length in Wavelengths 19:39 Calculate Length in Inches from Wavelengths 22:18 STEP 7 = Determine the lambda(Stub) 26:47 STEP 8 = Calculate the length of the coax for the Stub (Reactance Eliminating) 27:42 Final comments and Toodle-oots :-)
