# Designing Passive Components ## When to Use - Designing spiral inductors or interdigital capacitors for RF circuits - Extracting inductance, capacitance, or self-resonant frequency from passive components - Creating ring or split-ring resonators for filtering or metamaterial applications - Designing coupled-line or Marchand baluns for balanced-to-unbalanced conversion - Building Schiffman phase shifters or radial stubs ## When NOT to Use - Designing transmission lines (microstrip, stripline, CPW) — use `matlab-design-pcb-txline` - Designing filters (bandpass, lowpass, bandstop) — use `matlab-design-pcb-filter` - Designing couplers or splitters — use `matlab-design-pcb-coupler` - Setting up substrate materials — use `matlab-manage-pcb-material` - Running EM analysis after design — use `matlab-analyze-em` ## Typical Workflow 1. **Before:** `matlab-manage-pcb-material` — set up substrate and conductor 2. **This skill:** Design the passive component (inductor, capacitor, balun, resonator) 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 → `mat

What does the matlab-design-pcb-passive skill do?
Spiral inductors, interdigital capacitors, baluns, resonators, phase shifters for impedance matching, DC blocking, and bias tees.

How do I install it?
Run `npx skills add matlab/matlab-agentic-toolkit --skill matlab-design-pcb-passive --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.
