Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A radio station uses an RF amplifier with the following S-parameters: S11 = 0.2, S12 = 0.03, S21 = 3.0, and S22 = 0.1. If it connects a load with ZL = 60 Ohms, find the value of Γin and discuss its implications for signal integrity.

💡 Hint: Examine the impact of potential reflection limits on signal quality.

Challenge 2 Hard

Design a matching network for an RF amplifier with S-parameters given. Discuss how you would approach ensuring minimal reflections using the input reflection coefficient.

💡 Hint: Focus on impedance transformation techniques you might use.
