Question
Download Solution PDFWhich of the following is used for impedance inversion in a transmission line?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- The load impedance, ZL at the end of the transmission line must match to its characteristic impedance, Z0 Otherwise there will be reflections from the transmission line’s end.
- A quarter-wave transformer is a component that can be inserted between the transmission line and the load to match the load impedance ZL to the transmission line’s characteristic impedance Z0.
- The input impedance of a quarter-wave transformer is given as:
\({{\rm{Z}}_{{\rm{in}}}} = \frac{{{\rm{Z}}_0^2}}{{{{\rm{Z}}_{\rm{L}}}}}\;\).
Observation:
We observe that when ZL is low i.e. zero then Zin will be High i.e. Infinity and vice versa.Last updated on May 30, 2025
