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.
