# 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` ## Typical Workflow 1. **Before:** `matlab-manage-pcb-material` — set up substrate and conductor 2. **This skill:** Design the coupler or splitter 3. **Check mesh/memory:** `memoryEstimate(obj, fc, 'RetainMesh', true)` — inspect auto-mesh density before committing to a full solve 4. **After:** `matlab-analyze-em` — validate S-parameters → `matlab-optimize-pcb-design` — tune dimensions → `matlab-integrate-pcb-circuit` — cascade into

What does the matlab-design-pcb-coupler skill do?
Wilkinson, branchline, ratrace, directional couplers, corporate dividers, Rotman lenses for power splitting and beam-forming.

How do I install it?
Run `npx skills add matlab/matlab-agentic-toolkit --skill matlab-design-pcb-coupler --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From matlab/matlab-agentic-toolkit, a repository with 868 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
