Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An RF component has the following S-parameters: S11 = 0.3, S21 = 2.0, S12 = 0.02, S22 = 0.1. Calculate the input reflection coefficient when connected to a load with an impedance of 75 Ohms.

💡 Hint: Focus on calculating each component step-by-step and substituting carefully.

Challenge 2 Hard

Describe how a change in S12 affects the overall performance of a bilateral RF amplifier and provide numerical examples to support your claim.

💡 Hint: Examine how reflections combine with gain to influence the dynamic behavior of the system.
