Micro-miniature RF connectors support high frequencies and high data rates​


MHF series from I-PEX supports a wide range of RF technologies

I-PEX offers a complete solution for low-profile, micro-miniature RF connections to an antenna to enable smart sensors or other end-node devices to communicate wirelessly to a central control system.


The I-PEX MHF® series of micro-miniature RF solutions is ideal for connections in high-speed RF systems including Wi-Fi®, 4G mobile, 5G at mmWave and sub-6 GHz frequencies, Bluetooth®, GPS, WiGig, M2M, IoT, SigFox, WiSUN, NB-IoT and LoRa networking. I-PEX also offers an extensive line of micro-RF connectors for Wi-Fi 6/W-Fi 6E applications.


The MHF series is suitable for RF systems requiring a maximum voltage standing-wave ratio of 1.5. MHF connectors can be supplied with a locking solution that improves signal reliability in the field without relying on epoxy or other mechanical retention measures. This helps to reduce system cost and maintains signal integrity.  


I-PEX supplies complete MHF cable harnesses in multiple configurations:

  • MHF-to-MHF
  • Blunt-cut
  • Strip-and-tinned

A value-added option is orientation in 90° increments. I-PEX can also produce jacket cut-outs or windows for grounding using I-PEX MP-A clamps, or for a secondary process implemented at the customer’s production facility.
