SINGLE& DOUBLE STUB MATCHING TECHNIQUES PROF. MADHURI MAHENDRA PATIL Department of Electronics and Telecommunication PRAVIN PATIL DIPLOMA COLLEGE, BHAYANDAR I. Introduction In this paper, we will try to focus on narrowband single stub and double stub matching. We will use Smith Chart tool for solving impedance matching problems.done on the smith chart. SingleStub Matching Example Step 1: Plot the normalized load impedance (1. 46j0. 84), and draw a circle through that point, centered at 1 j0. Get the normalized load admittance by drawing a line from Z LN through 1j0 until you intersect the circle you drew on the other side. single stub matching example smith chart
Singlestub matching of transmission lines to loads. A worked example. This page illustrates the use of the SMITH chart in a simple series stub matching calculation. In our example, the SMITH chart construction to find the stub length is shown in the next picture.
We want to match this load at 2 GHz to a 50 W transmission line by using the single stub matching method. Either short circuit or open circuit stub can be used. Show the matching process on the Smith chart and find d and l in each case. Overview of stub tuning examples using the Smith chart to match RF lines to various loads. Having the ability to design these matching circuits on the fly can be very handy if you ever find yourself working in the RF field both because it can be faster than calculation, as well as being a great tool for visualizing what is going on.single stub matching example smith chart Single stub impedance matching Impedance matching can be achieved by inserting another transmission line (stub) as shown in the diagram below These locations correspond to the same points on the Smith chart. 1 2 stub Single stub matching problems can be solved on the Smith chart
