CoreHC™ Ganged Interconnect System

CoreHC™ is a high-performance multi-port interconnect system targeted for high-density boards where space is limited. Available in 2.5 mm and 4.0 mm spacing pitch, it offers reduced trace lengths and higher signal integrity compared to boards using traditional SMA and Precision RF-type connectors. On average, there is 4x higher available bandwidth for signals in the same real estate as SMA connectors.

CarlisleIT’s unique compression force design results in easy and rapid connectivity of high-frequency signals on the board. The 2.5 mm solution is designed for demanding bandwidths up to 65 GHz. Standard products are available in single and dual row 2-, 4-, 6-, 8-, 10-, and 16-channel configurations. Since there are configurations using single or multiple channels, board size can be optimized accordingly.

Vertical Mount

The vertical mount attachment solution eliminates the board-side connector or interposer by offering a direct connection of signals between the traces and pads on the PCB footprint and the compression pins on the cable assembly.

Edge Mount

A board-side interposer is required for an edge-mount-type solution. Optimized footprints and layouts are available upon request.

Right-Angle Mount

With a maximum connector height of only 9.08 mm, right-angle CoreHC cable assemblies are very useful in transmitting and receiving high-frequency signals up to 65 GHz to and from low-profile-height printed circuit boards to analyzers and other sub-systems. Similar to edge-mount and vertical-mount configurations, the right-angle CoreHC solution is offered with 3.5 mm, 2.92 mm, 2.40 mm, or 1.85 mm precision RF connectors on the cable side, depending on the required frequency of operation. The right-angle CoreHC solution is available in 2-, 4, 6-, 8-, and 16-channel configurations.

Mounting CoreHC


PEM nuts need to be installed on the back of the PCB to mount the CoreHC interconnect cable assembly firmly in place. We offer six types of PEM nuts for different board thickness profiles as follows:

  1. 0.062" (1.57 mm)
  2. 0.125" (3.18 mm)
  3. 0.0394" (1.00 mm)
  4. 0.093" (2.36 mm)
  5. 0.15" (3.81 mm)
  6. 0.197" (5.00 mm)
