Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given S-parameters, determine the stability of a network. S11 = 0.15, S22 = 0.3, S12 = 0.6, S21 = 0.6. Calculate K and Δ. Are they stable?

💡 Hint: Review the formulas for stability criteria and plug your values carefully.

Challenge 2 Hard

Improve the network stability in the previous challenge problem by suggesting modifications in design. What parameters would you have to modify?

💡 Hint: Consider ways to enhance isolation or feedback in circuits.
