  • Question

  • A (75 - j 40) W load is connected to a co-axial line of z0 = 75? at 6 MHz. The load matching on the line can be accomplished by connecting


  • Options
  • A. a short circuit stub at the load
  • B. an inductance at the load
  • C. a short circuit stub at a specific distance from the load
  • D. a capacitance at a specific distance from the load

  • Correct Answer
  • an inductance at the load 

    Explanation
    ZL = 75 - J . 40, ZC = 75 W, f = 6 mHz

    Given ZL is capacitive, so proper matching, load must be inductive.
