Patent number: 9209116Abstract: A semiconductor device package includes a solid metal base with a top surface and an electrically conductive chip mounting area on the top surface. First and second pairs of conductive leads are attached to the base and extend away from one another in opposite directions. First and second amplifiers are attached to the top surface and are electrically connected to the first and second pairs of leads. The first pair is separated from the second pair by a horizontal gap between inner edge sides of the leads. A reference line in the horizontal gap that extends perpendicular to edges of the base divides the chip mounting area into first and second chip mounting sections. An area of the first chip mounting section is smaller than an area of the second chip mounting section. The first and second leads have a smaller width than the third and fourth leads.Type: GrantFiled: June 5, 2014Date of Patent: December 8, 2015Assignee: Infineon Technologies AGInventors: Alexander Komposch, Soon Ing Chew, Herman Hugo, Simon Ward

Patent number: 8110915Abstract: An RF semiconductor package includes a substrate having generally planar top and bottom surfaces. The substrate includes a metallic base region and one or more metallic signal terminal regions extending from the top surface to the bottom surface, and an insulative material separating the metallic regions from one another. The bottom surface of an RF semiconductor die is surface-mounted to the base region at the top substrate surface. The RF semiconductor die has a terminal pad disposed at a top surface of the RF semiconductor die. The terminal pad is electrically connected to one of the signal terminal regions at the top substrate surface. A lid is attached to the top substrate surface so that the RF semiconductor die is enclosed by the lid to form an open-cavity around the RF semiconductor die. The base and signal terminal regions are configured for surface-mounting at the bottom substrate surface.Type: GrantFiled: October 16, 2009Date of Patent: February 7, 2012Assignee: Infineon Technologies AGInventors: Donald Fowlkes, Soon Ing Chew
