Challenge Problems

Push your limits with challenges.

Question 1

Design a stub matching network for a specific RF antenna with a 50-ohm impedance, specifying whether to use an open-circuited or short-circuited stub. Justify your choice based on the antenna's operating frequency.

πŸ’‘ Hint: Reflect on how the type of stub influences the overall impedance.

Question 2

Given a complex RF system, propose a stub matching strategy to ensure minimal signal reflection, detailing the calculations or methods you would take to determine stub length.

πŸ’‘ Hint: Consider using formulas for calculating the electrical length based on frequency and speed of signal propagation.
