The RF module includes various semiconductor active devices disposed upon an insulating substrate. The RF module can be a front-end module (FEM) with one or more charge pumps as active devices. A polysilicon web extends between and underneath the devices to create a network of ground paths across a surface of the insulating substrate.

The disclosed solution also reduces RF noise leakage into the substrate, and can reduce RFI between neighboring RF modules.
