(a) A 10m lossless transmission line having characteristic impedance Zo= 10092 and capacitance per unit length C= 50 pF/m, is terminated with a load of 7592 and is being operated at frequency of 200 MHz with a wave speed of u, 2x10 m/s. Find the following: (i) The voltage standing wave ratio, VSWR, (ii) the total value of transmission line inductance, [5 marks] [5 marks] (iii) the phase constant B. [4 marks] (iv) the input impedances of the line Zin [5 marks] (v) the new terminated load that should be connected to make the reflected voltage equal to 10 % of the incident voltage. [6 marks] (b) At an operating frequency of 100MHz, it is desired to use a section of lossless transmission line terminated in an open circuit to construct an equivalent load with reactance X= 50 2. If the characteristic impedance of the line is 75 £2 and the phase velocity is 1.5x10 m/s, what is the shortest possible line length that would exhibit the desired reactance at its input?
