4.1-9.5 Connectors

4.1-9.5 Connectors

Amphenol RF offers a full range of 50 Ohm 4.1-9.5 connectors, adapters and cable assemblies. These interconnect products are engineered for the wireless market and ideal for applications requiring low passive intermodulation, or PIM.

4.1-9.5 interconnects are low PIM tested, making them ideal for mobile communication systems and wireless applications. These connectors are able to match the performance and mechanical robustness of a 7-16 or N-Type connector in a smaller footprint.

The Amphenol version features a patented ultra-slim push-pull coupling system which allows quick installation and ensures positive locking and high retention.

Features and Benefits
  • Excellent low PIM performance
  • High reliability threaded coupling mechanism
  • Supports a wide variety of cable types
  • Field replaceable connectors available
  • Distributed Antenna Systems (DAS)
  • Base Stations
  • Antennas
  • Cell Installations
  • RFID
