A circuit-board interposer includes contacts on a top surface and a bottom surface and includes a millimeter-wave coaxial transition structure formed using contacts on the top surface and vias extending into the interposer. A first via extends into the interposer to a first depth and is surrounded by additional vias that penetrate the interposer to a second depth smaller than the first depth. The interposer also includes a hollow conductive waveguide structure formed within the interposer that extends from the second depth to a third depth that has a first end and a second end. The first via extends into the waveguide at the first end and an aperture is present at the second end. The coaxial transition and the waveguide together are configured to couple millimeter-wave energy from a feed contact on the top surface of the interposer and direct it to the aperture.

Interposers with millimeter-wave coaxial-to-waveguide transistions

A compact integrated circuit (IC) that outputs millimeter-wave energy can be assembled into a highly compact package that can utilize ultrasmall contacts and/or contacts arrange with nonstandard pitch. The millimeter-wave IC can be assembled onto an interposer that includes an integrated transition configured to be coupled to a millimeter-wave waveguide on a printed circuit board having contacts that have a standardized size and pitch.
