railway RRB JE (CBT I + CBT II) Mock Test 2024 Electromagnetic Theory Electromagnetic Wave Propagation Standing Wave and Standing Wave Ratio
It is required to match a 200Ω load to a 300Ω transmission line to reduce the SWR along the line to 1. What must be the characteristic impedance of the quarter-wave transformer used for this purpose, if it is connected directly to the load?
1
225Ω
2
300Ω
3
72Ω
4
