An electrical component assembly () comprising a heat sink (), electrical components (--) arranged on the heat sink () and an interconnect () electrically connecting the electrical components (--). The heat sink () is integrated with the electrical interconnect () such that the electrical interconnect () is at least partly arranged in and extends along a cavity () of the heat sink (). The electrical interconnect () comprises at least one layer () of deposited material comprising electrically conductive material forming one or more interconnecting conductors (). The interconnect further comprises one or more dielectric layers () of deposited material which isolate the one or more interconnecting conductors (). The one or more interconnecting conductors () electrically contacts the respective electrical component in a respective contact area (-) of the cavity (). The electrical components (--) are arranged on the heat sink () such that a respective one of one or more electrical contacts (-) of the electrical components align with a respective interconnecting conductor ().

Electronic component assembly, an antenna array system, and electronic device, and a method for manufacturing an electrical component assembly

In an example embodiment, a system comprises a chain of serially coupled nodes, including a central processing node (CPN) and one or more radio communications nodes (RCNs). The CPN couples to a first RCN in the chain via a dielectric waveguide (DWG) link and any further RCNs in the chain are successively connected in serial fashion from the first RCN via further (DWG) links. The CPN generates outbound radio carrier signals that are waveguide-propagated in a downstream direction of the chain, for over-the-air (OTA) by targeted ones of the RCNs, while radio carrier signals received via OTA reception by respective ones of the RCNs are waveguide propagated as inbound radio signals in an upstream direction of the chain, for processing by the CPN. Advantages from he contemplated system include greatly simplified implementation of the RCNs, with lower cost and power consumption. Further, strategic placement of failover CPNs and DWG links provide for continued operation in the face of CPN or DWG link failures.
