Question 1
You connect a 50-ohm load to a transmission line with a characteristic impedance of 75 ohms. What is the reflection coefficient?
π‘ Hint: Don't forget about the formula and remember to substitute correctly!
Question 2
A transmission line with SWR of 5:1 is connected to a load. What could this indicate about the load impedance, and how can it be improved?
π‘ Hint: Consider typical values for SWR and their meaning in terms of matching.
