Abstract
A connector includes a conductive body with a central bore along a central axis. The body includes a mounting face for positioning adjacent a mounting surface of a circuit member and for removably engaging a reference pad of the circuit member. A center conductive contact includes a board engaging end for removably engaging a signal pad of the circuit member. An inner dielectric insert is positioned between the conductive body and the center conductive contact. The conductive body, the center conductive contact and the inner dielectric insert are configured to operate at a frequency of at least 40 GHz with a return loss of greater than 20 dB.

A connector for mounting on a mounting surface of a circuit member, the circuit member including a signal pad and a reference pad, comprising:
- a conductive body having a central bore along a central axis, the coaxial body including a mounting face for positioning adjacent the mounting surface of the circuit member and removably engaging the reference pad, the central bore including a first mating section, a second dielectric insert section and a third board mount section sequentially along the central axis, the first mating section having a first diameter, the second dielectric insert section being located between the first mating section and the third board mount section and having a second diameter smaller than the first diameter, the third board mount section being located between the second dielectric insert section and the mounting face and having a third diameter smaller than the second diameter;
- a center conductive contact positioned along the central axis and extending within the first mating section, the second dielectric insert section and the third board mount section of the conductive body, the conductive contact including a mating contact end for mating with a mating component and a board engaging end for removably engaging the signal pad of the circuit member;
- an inner dielectric insert positioned within the second section of the conductive body between the conductive body and the center conductive contact;
- a first transition region between the first mating section and the second dielectric insert section and a second transition region between the second dielectric insert section and the third board mount section, the first and second transition regions being configured to minimize the impact of changes in geometry and dielectric material between the center conductive contact and the conductive body.
