Challenge Problems
Push your limits with challenges.
Question 1
A 50 Ω transmission line has a load impedance of 20 + j30 Ω. Normalize it and plot it on the Smith Chart. Determine if an open-circuited stub will provide the necessary matching.
💡 Hint: Don't forget the process of plotting and checking it against the characteristic impedance!
Question 2
Using the Smith Chart, design a two-stub matching network to match an impedance of 50 - j40 Ω to a line with Z0 = 75 Ω. Specify the stub locations and lengths.
💡 Hint: Keep track of the path taken and reflect the necessary components to achieve a matched network.
