HD-EFI Product Series
50 Ohm Micro-Miniature Interface
Overview
The HD-EFI product series is a micro-miniature interface
designed to allow large board tolerance stack ups, blind
mating, and multiple RF lines. This is achieved by
maximizing radial and axial float while maintaining high
frequency RF performance.
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 1.4mm of axial float, and 1.4mm of radial float,
with a maximum float angle of 5 degrees.
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.
