Challenge Problems
Push your limits with challenges.
Question 1
You are given a load with an impedance of 50 + j30Ξ©. How would you use a single-stub matching network to achieve a match at 1GHz frequency?
π‘ Hint: Remember to analyze both the real and reactive parts of the impedance.
Question 2
Design a single-stub matching network that connects a 75Ξ© load to a 50Ξ© source. What length of stub would you need if you aim to cancel a reactance of -j25Ξ©?
π‘ Hint: Find the point on the Smith Chart that corresponds to 75Ξ©, and calculate backward for the stub length.
