Topic: Transmission Lines

A lossless transmission line with characteristic impedance Z_0 = 50 ohm is 30 m long and operates at 2 MHz. The line is shorted at the load, if the phase velocity = 0.6 times the velocity of light, the input impedance of the line is:

  • A. 75 < 90° ohm
  • B. 50 / $\sqrt{3}$ < 180° ohm
  • C. 100 / $\sqrt{2}$ < 180° ohm
  • D. 75 / $\sqrt{2}$ < 270° ohm
