Amphenol RF's line of 2.2/5 connectors are a compact version of the previously released 4.3/10 connector series, with a 53% smaller footprint. This connector series is lightweight and can accommodate thick, low loss cables up to a half inch. The robust design makes these connectors ideal for both indoor and outdoor applications.

The 2.2/5 connector series is designed to meet the needs of applications which require low PIM in order to avoid interference in network quality during high speed data transmission. These connectors offer flexibility in installation with the ability to blind mate and are IP68 rated in the mated condition.


  • Excellent low PIM performance up to 20 GHz
  • Lightweight, compact design
  • Optimized for 1/4, 3/8, 1/2 inch corrugated cables
  • Ideal for outdoor applications


  • Small Cells
  • Mobile Networks
  • Distributed Antenna Systems (DAS)
  • Low Power Base Stations
  • In-Building Architecture
  • MIMO Antennas
  • Test & Measurement
