Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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!

Challenge 2 Hard

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.
