What problem does it solve?

This Skill solves the challenge of building accurate MATLAB RF Toolbox signal integrity (SI) channel models from real measured S-parameter blocks and frequency-dependent interconnect behavior.

Core Features & Use Cases

• Cascaded channel modeling: Cascade measured nport S-parameter blocks with lossy transmission lines and lumped parasitics in an RF Toolbox circuit.
• Frequency-dependent loss: Model skin-effect and dielectric loss using txlineWRLGC or txlineWtable, then extract insertion loss, return loss, and crosstalk.
• Mixed lumped-distributed topologies: Combine vias, connectors, PCB segments, and multi-port blocks, with correct termination and port exposure for faithful S-parameter extraction.

Quick Start

Ask your AI agent to build an SI channel circuit that cascades a txlineWRLGC PCB trace, a lumped via subcircuit, and another txlineWRLGC segment, then extract and plot S21 insertion loss and S11 return loss over a specified frequency range.
