Designing Couplers and Splitters

When to Use

• Designing Wilkinson splitters (equal, unequal, wideband) for power division
• Creating branchline or ratrace couplers for quadrature or sum/difference networks
• Building corporate power dividers for array feed networks
• Designing directional couplers for signal sampling
• Creating SIW splitters or Rotman lenses for beam-forming

When NOT to Use

• Designing transmission lines — use matlab-design-pcb-txline
• Designing filters — use matlab-design-pcb-filter
• Designing passive components (inductors, capacitors, baluns) — use matlab-design-pcb-passive
• Cascading couplers with other components — use matlab-integrate-pcb-circuit
• Optimizing coupler performance — use matlab-optimize-pcb-design
