A 50 M transmission line is driven by a source impedance of 50 2 and terminated imperfectly by a 75 2 resistor in parallel with a 1 pF capacitor. Transmission line length = 10 cm, Velocity = 0.5c ● A) Using a simulation tool, plot the normalized impedance of the load at 1 GHz and also plot a frequency sweep from 10 MHz to 10 GHz. B) Using a simulation tool, plot the normalized input impedance of the transmission line at 1 GHz and also plot a frequency sweep from 10 MHz to 10 GHz. C) What effect does changing the transmission line length have? Can this be used to match the impedance? D) Plot the frequency response form the source voltage to the load voltage using a simulator from 10 MHz to 10 GHz. E) Replot the frequency response when the load is 50 . Comment on the importance of precise termination at high frequencies. F) Design a matching network for the load at 1 GHz. G) Plot the normalized input impedance of the transmission line with matched load from 10 MHz to 10 GHz.
