The HD-EFI connector series is a board-to-board RF solution, originally designed for the broadband and wireless marketplaces. It is available in common PCB jack and cable plug configurations, with an assortment of bullet adapters to accommodate many board to board spacing options.

The HD-EFI interface is a proprietary design, allowing for a very stable RF signal over the full axial range of the connector system. It has generous “float” to compensate for the axial and radial misalignment tolerance common in small package sized applications.

The interface is available as a 50 Ω connector system with a performance of DC to 6 GHz.
