It is known that the voltage along the transmission lines is: Ve 12 +2e112 for zo V(z)= | -1 e 12 +V, e j2 for z>0 The length of the resistor is very small («i). Determine the values of constants V, and V 5 Carefully consider the voltages on the two transmission lines below: (2) -3.0e - 1.0 eV V(z) AV where A is an unknown constant. The characteristic impedance of the second transmission line is also unknown I(2) I (2) (z) Z = 4002 1000 Za = V.(2) z 0 Apply boundary conditions to determine the values of unknown constant A and characteristic impedance Zoz. 4/6 6 A lossless tranmission line of length of length is terminated with a normalized load impedance of: z = 2.0 + jx, All that is known about load reactance x; is that it is positive (x>0) The normalized input impedance of this transmission line is: z = 0.2 Use a Smith Chart to determine the length of this transmission line in wavelengths. Determine the value of load Z that will result in the maximum absorbed power. 7 How much power would this be? Z-100 + 50 1.0 Z = 50 ( = 1/8
