Question 4 [15 marks] A load of Z₁ = 25 + j25 № is to be matched to a Zo = 50N system (i.e. Zin 50 M). L 50Ω a. [6 marks] Describe how this can be done with a section of open-circuited Zo transmission line connected in parallel to the load. Support your answer with a sketch. b. [2 marks] At 3GHz, find the minimum length (in m or mm) of this piece of transmission line, assuming that the dielectric in the line has ER = 1. c. [3 marks] If the parallel line was short instead of open-circuited, what would the minimum line length be? d. [2 marks] Repeat part (b) for a dielectric-filled transmission line (år = 2.25). e. [2 marks] Would this method work for matching a load with arbitrary impedance? Why, or why not? =
