Abstract:
1. An apparatus, comprising: a substrate; first and second radio frequency devices mounted on the substrate; a plurality of wirebond structures disposed on the substrate between the first radio frequency device and the second radio frequency device; a first conductive ground layer disposed at least partially below the first radio frequency device and in electrical contact with one or more of the plurality of wirebond structures; a second conductive ground layer disposed at least partially below the second radio frequency device, the second conductive ground layer being at least partially electrically isolated from the first conductive ground layer; a molding dimensioned to at least partially encapsulate the first and second radio frequency devices and each of the one or more of the plurality of wirebond structures; and a first conductive top layer disposed above a top surface of the molding and in electrical contact with the one or more of the plurality of wirebond structures, such that the first conductive top layer, the plurality of wirebond structures, and the first conductive ground layer at least partially form a radio frequency barrier between the first radio frequency device and the second radio frequency device.
