QN Connectors

QN Connectors

Amphenol RF’s QN connector is a quick disconnect version of the N-Type connector with similar internal construction, which enables fast and easy matings with minimum space requirements.

The innovative alternative to N-Type connectors, the QN line is perfect for indoor and outdoor applications including base stations and cellular installations. These connectors have the same benefits as threaded connectors and can be terminated to larger cables and are designed to handle higher power requirements.

Features and Benefits
  • Operates at the same electrical performance as the N-Type up to 11 GHz
  • Snap-on interface for quick and easy installation
  • Rotatable 360° after connection for flexibility with installation
  • Base Stations
  • Data Communications
  • Routers
  • Switching Equipment
