1. A contact head comprising:
coaxial contacts configured for transmission of radio frequency (RF) signals or digital signals between a test system and a device under test (DUT), each of the coaxial contacts being configured to target a specific impedance, and each of the coaxial contacts comprising:
a coaxial structure having an open-curve shape, where a curvature of the open-curve shape is between two ends of the coaxial structure, the coaxial structure comprising a spring material that bends in response to applied force and that returns to the open-curve shape absent the applied force, the coaxial structure comprising a center conductor terminating in a contact pin and a return conductor separated by a dielectric from the center conductor, at least part of the center conductor and the return conductor comprising an electrically-conductive material; and
flexible contacts comprising the electrically-conductive material, the flexible contacts being electrically connected to the return conductor.
