Couplers & Dividers

1. Conceptual Intuition (L1)

• Power Splitting: Pizza slice analogy.
• Sampling power (Coupling) without interrupting the flow.
• Directionality: Measuring forward vs reflected waves.

2. Engineering Math (L2)

• Wilkinson Power Divider (using the isolation resistor).
• Directional Coupler metrics: Coupling Factor, Directivity, Isolation.
• Quadrature Hybrids (90 degree shift).

3. System Application (L3)

• Isolation failure mechanisms.
• Uneven split designs.
• Rat-race couplers for high power summing.
