Abstract: A component carrier which includes a stack having at least one electrically conductive layer structure and/or at least one electrically insulating layer structure, a first electronic component and a second electronic component arranged in the stack, a first block and a second block arranged in the stack below the first electronic component and the second electronic component, and a third block and a fourth block arranged in the stack above the first electronic component and the second electronic component, wherein said blocks are thermally conductive.

Abstract: A component carrier which includes a stack having at least one electrically conductive layer structure, at least one electrically insulating layer structure, and a recess being at least partially formed in the stack, optionally having an electrically conductive coating, and being configured as waveguide, wherein a plurality of edges delimiting the recess are formed by electrically conductive material of the at least one electrically conductive layer structure and/or of the optional electrically conductive coating.

Abstract: A component carrier includes a stack with at least one electrically conductive layer structure and at least one electrically insulating layer structure, and a microwave structure embedded at least partially in the stack. The microwave structure configured for exciting a microwave propagation mode and having at least two stack pieces being interconnected with each other at an electrically conductive connection interface.
