Abstract:
A package for high frequency components, comprising:a cover with a lower surface; a multilayer base including a dielectric layer between a top layer and a bottom layer, and the top layer and the bottom layer each including an electrically conductive ground plane portion, I/O pad portion, and differential I/O pad portion, with each of the corresponding portions coupled to one another by vias within said dielectric layer, and the multilayer base coupled to the lower surface of the cover and the combined multilayer base, and cover defining an electrically shielded cavity within the package; and an electrical component located within the electrically shielded cavity and the electrical component differentially coupled electrically through the differential I/O pad portion on the top layer to corresponding differential pad portion on the bottom layer and an RF energy radiated from said electrical component during operation substantially contained within the package by the electrically shielded cavity.
