Patent ID: 8110915

Claim:
An RF semiconductor package, comprising: a substrate having generally planar top and bottom surfaces, the substrate comprising a metallic base region extending from the top surface to the bottom surface, one or more metallic signal terminal regions extending from the top surface to the bottom surface without extending laterally outward from the substrate, and an insulative material separating the metallic regions from one another; an RF semiconductor die having a bottom surface surface-mounted to the base region of the substrate at the top surface of the substrate, the RF semiconductor die having a terminal pad disposed at a top surface of the RF semiconductor die, the terminal pad being electrically connected to one of the signal terminal regions of the substrate at the top surface of the substrate; a lid attached to the top surface of the substrate so that the RF semiconductor die is enclosed by the lid to form an open-cavity around the RF semiconductor die; and wherein the base region and each signal terminal region of the substrate are configured for surface-mounting at the bottom surface of the substrate.
