Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
