Challenge Problems
Push your limits with challenges.
Question 1
Design an impedance matching network for a scenario where an RF amplifier outputs 100 ohms and a 75-ohm load is connected. Describe the steps and calculations involved.
💡 Hint: Use the formula for calculating the reactance needed to achieve the target impedance.
Question 2
Evaluate the impact on signal integrity when an amplifier with a 50-ohm output is connected to a 100-ohm load without any matching. Discuss the frequency response implications.
💡 Hint: Consider the reflection coefficient and how it defines the amount of reflected power.
