P7.32. Solution of a single-stub matching problem by using the Smith chart. A trans- mission line of characteristic impedance 60 2 is terminated by a certain load im- pedance. It is found that the SWR on the line is equal to 4.0 and that the first voltage minimum of the standing-wave pattern is located to be at 0.2A from the load. Using the Smith chart, determine the location nearest to the load and the length of a short-circuited stub of characteristic impedance 60 2 connected in parallel with the line required to achieve a match between the line and the load. 0.19 0.11 0.12 0.13 0.1 0.14 0.09 0.39 0.38 0.37 0.4 0.36 0.15 0.08 0.41 100 90 0.07 0.42 110 80 0.35 0.16 120 70 0.34 0.17 0.43 0.33 130 0.18 B 0.32 50 0.31 0.05 0.45 +++++ CONTRA O 0.49 0.48 H ENGTHS TOW+++ 0.46 0.47 140 0.06 0.44 96 0.2 REFLECTION CONT 0.23 0.04 -150 TT 0.8 0.45 0.05 0.6 -140 0.29 0.44 0.06 -130 0.07 0.43 0.08 -120 50 0.42 0.13 0.31 0.09 60 0.41 -100 -70 0.17 0.32 0.16 0.33 0.12 0.13 0.14 0.15 H 0.34 0.39 0.38 0.35 0.37 0.36
