Designing Transmission Lines

When to Use

• Designing microstrip, stripline, or CPW transmission lines for impedance control
• Modeling differential pairs with or without aggressor traces for NEXT/FEXT crosstalk
• Analyzing 2D cross-sections for fast per-unit-length RLGC extraction
• Creating SIW (substrate integrated waveguide) lines
• Using design() to auto-size lines for target impedance at a given frequency

When NOT to Use

• Building custom PCB structures from shapes — use matlab-assemble-pcb-layout
• Setting up substrate or conductor materials — use matlab-manage-pcb-material
• Running S-parameter or field analysis after design — use matlab-analyze-em
• Cascading transmission lines with other components — use matlab-integrate-pcb-circuit
