Patent ID: 8808010

Claim:
A coaxial socket assembly for use in a test system, the test system configured to align at least a portion of an electronic device with a plurality of aligned connectors, the coaxial socket assembly comprising: a socket comprising: a metal structure having a plurality of openings, the plurality of openings spaced to accommodate the plurality of aligned connectors, at least one opening in the plurality of openings extending through a thickness of the metal structure, the at least one opening having an annular inner surface, the annular inner surface being proximal to at least a portion of a conductive outer surface of at least one aligned connector of the plurality of aligned connectors in the test system; and an insulation layer provided on the annular inner surface; and a socket retainer comprising: a metal retainer including a plurality of annular guide holes extending through the metal retainer and configured to accommodate the plurality of aligned connectors when the socket retainer is aligned with the socket, at least one of the annular guide holes of the plurality of annular guide holes having an annular retainer surface; and a retainer insulation layer provided on the annular retainer surface, the retainer insulation layer configured to align with the insulation layer provided on the annular inner surface when the socket retainer is aligned with the socket, the socket retainer and the socket configured to present a cavity interface to the at least one aligned connector; wherein the socket retainer and the socket are configured to present a substantially constant impedance across the cavity interface to an electrical signal provided across the at least one aligned connector.
