Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

In a given RF amplifier design, you find that S12 is non-zero. Describe the steps you would take to assess whether your design remains stable.

💡 Hint: Calculate K and Delta before using graphical tools.

Challenge 2 Hard

Given S-parameters: S11 = 0.5, S12 = 0.4, S21 = 5.0, S22 = 0.7. Compute K and Δ. Determine whether the amplifier is unconditionally stable.

💡 Hint: Show all calculations step-by-step.
