What problem does it solve?

This skill solves the problem of designing RF/microwave PCB couplers and power splitters without getting lost in component-specific topology choices and tedious sizing across Wilkinson, branchline, ratrace, directional, corporate dividers, SIW splitters, and Rotman lenses.

Core Features & Use Cases

• Coupler/Splitter Design Across Multiple Topologies: Generate MATLAB objects and size them appropriately for the requested center frequency, including equal/unequal/wideband Wilkinson splitters, hybrids, directional couplers, corporate N-way dividers, SIW splitters, and Rotman lenses.
• Guided Validation Workflow: Recommend a practical sequence that includes pre-solve mesh/memory estimation, EM S-parameter computation, and follow-on analysis/optimization/circuit integration to meet RF performance goals.
• Avoid Common Missteps by Routing to Specialized Skills: Direct you away from transmission lines, filters, generic passive components, EM analysis-only tasks, material-only setup, and multi-component cascading that belong to other skills.

Quick Start

Ask: “Design a 5 GHz wideband Wilkinson splitter on an FR4/Teflon substrate, validate S-parameters, and report the isolation between outputs.”
