QN is a new type of connector introduced by HUBER+SUHNER, which has similar performance as N connector but is easier to install
The QN series from Huber+Suhner are 50 Ω coaxial RF connectors that use a snap‑lock mechanism instead of a threaded nut, providing faster and torque‑free assembly. Their compact dimensions allow higher packaging density and compatibility with TNC‑size flanges.
Technical data include a frequency range up to 11 GHz (optimized to 6 GHz), dielectric withstanding voltage of 2500 V rms, working voltage of 1000 V rms, and an IP68 environmental rating. Mechanical specifications list 2 100 mating cycles, 30 N engagement force and a retention force of 2450 N, while the connectors operate from –40 °C to +125 °C.
