To design a Wilkinson power divider in MATLAB, specify the target center frequency and substrate material. The tool sizes the component, generates the appropriate MATLAB object, and validates EM behavior using S-parameters and isolation metrics.

The best way to validate S-parameters for an RF PCB coupler is to run a pre-solve mesh and memory estimation, compute EM S-parameters using interpolated sweeps, and then analyze coupling, directivity, and isolation to confirm performance.

Yes, you can use MATLAB to design SIW splitters and Rotman lens beam-forming networks. The tool sizes these topologies for a target center frequency and validates their electromagnetic behavior through S-parameter computation.

No, this approach does not support transmission lines, filters, or generic passive PCB components. It focuses strictly on couplers and power splitters, routing transmission line and filter tasks to specialized skills to avoid common design missteps.

To analyze isolation between output ports on a wideband splitter, complete the S-parameter computation and then run the optional coupling, directivity, and isolation analysis provided in the validation workflow to measure RF performance.

You should avoid using this skill for pure EM extraction, material-only setup, circuit cascading, or generic PCB element design. It is strictly scoped to selecting, sizing, and validating coupler and splitter topologies like branchline and ratrace hybrids.
