Choose one of the following problems, solve it and share the solution in the forum. Perform a critical analysis on the group members’ contributions and reply this in the forum.
1. A lossless transmission line has a characteristic impedance of = 60Ω and the load at the end of the line has an impedance of = 45 + 95Ω. Using the Smith Chart, find: a. Reflection coefficient Γ (magnitude and phase), and the VSWR. b. The input impedance if the line is 0.75 long. c. The length of the line, necessary to make the input impedance real and the value of the impedance in this point.
3. A 45Ω lossless transmission line has a = 45 − 60Ω. If it is 200 long and the wavelength is 23 . Find and probe with the smith chart: a. Input impedance. b. Reflection coefficient. c. VSWR
4. A transmission line of length = 0.35 has an input impedance = 25 + 45Ω . Using the Smith Chart, find the load impedance if = 75Ω.
5. A load = 45 − 60Ω is connected to a transmission line with = 75Ω. The line is = 0.35 . Find the input impedance and at least two line lengths where the input impedance is real. Use the Smith Chart to Solve the exercise.
2. A transmission line has the following parameters:, = 2/ , = 45 / , = 1.2/ and = 4Ω/ . It has a generator supplying 200 at = 5 10 / and in series with a resistance of 200Ω. The load has an impedance of 300Ω. Find the input voltage and current.
