Question
A lossless transmission line has a characteristic impedance of Zo= 502, a load impedance of
ZR = 75-j75 2 and its operating frequency is fo = 300 MHz. Use the attached Smith chart
to evaluate the following parameters: (Answer Only FOUR of the following questions)
1) The reflection coefficient |KR|ZOR, and the voltage standing wave ratio (VSWR).
2) The distance from the load to the nearest maximum and minimum voltage positions in
meter.
3) The input impedance at the source terminal (Zin), if the length of this transmission line
is 1.5 λ.
4) For the same transmission line, design a single parallel short circuit stub that makes
the transmission line matched to the given load. In your design, find the nearest
position of this stub from the load (d) and the length of this stub (Ls), both in meter.
5) For the same transmission line, design a series A/4 transformer that satisfying
matching with the above load. In your design, find the position of this transformer
from the load (d) in meter, and its characteristic impedance Zoi that has a value greater
than Zo.
