Abstract
An example contact head includes 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 is configured to target a specific impedance. Each of the coaxial contacts includes a coaxial structure having an open-curve shape. The coaxial structure includes 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 includes 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 include an electrically-conductive material. Flexible contacts on the coaxial contact include the electrically-conductive material.
