The HD-EFI Series of Connectors

Micro miniature connector interface HD EFI by Amphenol RF

The HD-EFI product series is a micro-miniature interface designed to allow large board tolerance stack ups, blind mating, and multiple RF lines.

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, making them ideal for high-performance applications with a small package size.
