Amphenol RF has released newly developed HD-EFI product line. This 50 ohm micro-miniature interface is ideal for blind-mate situations and mating multiple RF lines between printed circuit boards. These connectors are designed specifically to maximize radial and axial float in board-to-board applications.
HD-EFI PCB jacks are available in through-hole, surface mount, and edge launch designs. The three-piece mating system uses a limited detent and a smooth bore PCB connector, joined by a floating bullet adapter in between. The generous gathering cone and unique bullet design allows for 1.4 mm of axial float, and 1.4 mm of radial float, with a maximum float angle of 5°.
These 50-ohm products have an operating frequency of dc to 6 GHz, making them ideal for high-performance applications with a small package size. The selection of PCB mounts and bullet lengths offer versatility for board launches and PCB stacking configurations.
HD-EFI bullet adapters are uniquely designed to provide a crash-proof mating, facilitated by the extension of the insulator beyond the adapter body. Used in conjunction with the smooth bore connectors, the mating system allows for easy alignment and a secure connection.
