In a circuit we have a source with 75 W impedance that we want to connect to a 300 W load with a transmission line with characteristic impedance of 75 W. To achieve maximum power transfer an inductor will be connected in series to the source.
a. Use the Smith Chart on the next page to get the minimum length of the line in wavelengths and the inductor reactance value. Write down the values here.
b. Use the input impedance formula, Zin, for a lossless line to get the value of the input impedance with the length given by the Smith Chart.
c. Compare the reactance of the Smith Chart and the formula.
