The spacing is frequently made l/4.This is called double stub matching. Double stub matching is preferred over single stub due to following disadvantages of single stub. 1. Single stub matching is useful for a fixed frequency .So as frequency changes the location of single stub will have to be changed. 2.The stub is added to the transmission line in parallel with the load, therefore it is easier to work with admittances since: T T Y Y Y Z Z Z + = 1 + 2 = 1 2 1 1 1 The method is a two-step process 1. Select the position of the stub (d) such that: Yd =Y0 +jB ⇒yd =1+jb (the real part of the impedance matches the line) 2.Therefore the “ double-stub” method was developed. We need to adjust two parameters to get a match. A few words about lab: We have two lab tasks on impedance matching. Single stub: We can’t “slide” the stub on the main line to adjust . d. Therefor we “adjust” the frequency. Double stub: Two stub lengths are adjusted.Question: Incorrect Question 5 0/2 pts The following information pertains to Questions 5 - 6.
