This is a 10 GHz Stub Low-pass filter, made using ADS.
First, build the component using the ADS DesignGuide/Smart Component Passive Circuit tool.
This is the original, equation-based simulation.
This is the substrate used for the Low-pass filter.
This is the Momentum simulation of the layout component.
This is the layout component for the 10 GHz Stub Low-pass filter component.
