Challenge Problems
Push your limits with challenges.
Question 1
You have two cascaded networks. The first has S-parameters S11 = 0.1, S21 = 3.0, S12 = 0.01, S22 = 0.2, and the second S11 = 0.3, S21 = 2.0, S12 = 0.02, S22 = 0.4. Calculate the total reflection coefficient at the input.
💡 Hint: Work step by step: 1) convert S-parameters, 2) multiply matrices, 3) find reflection.
Question 2
Analyze how the output match of the first network affects the input match of the second network given mismatches.
💡 Hint: Connect the mismatches back to the S-parameters for clarity.
