QN Series QN – coaxial connectors Description Content HUBER+SUHNER QN coaxial connectors are available with Description 283 50 Ω impedance. The frequency range extends to 11 GHz, Interface dimensions in mm/inches 283 depending on the connector and cable type, however most of Features 283 the QN connectors are return loss optimised for frequencies up Technical data 284 to 6 GHz. The interface is based on the inner dimensions of the Cable connectors 285 N connector but instead of a threaded coupling mechanism a Receptacles with solder end 289 snap-lock mechanism is used. QN eXtreme – XQN 290 QN calibration 291 The QN interface has a very similar performance to N, but in addition it offers an easier, faster and safe coupling operation, helping the customers to save significantly time during production of their systems. The packaging density of QN increased compared to N thanks to the fact that no torque spanner is required to fasten the coupling nut. Additionally the outer dimensions of QN are smaller than N, leading to the advantage that even TNC-size flanges can be used at QN connectors. Interface dimensions compared to N Plug (male) QN N Jack (female) QN N Features of QN connectors • Cycle time improvement for making RF connections (10 times faster to mount than threaded connectors) • No torque required • Higher packaging density • Free-rotating connection when mated (cable torsion relief) • Eliminates loosening problems associated with threaded connectors • Same performance as N • Best intermodulation performance thanks to the unique interface design HUBER+SUHNER QN – the cost effective solution for advanced RF interconnections! IP rating (interface, mated) IP68 HUBER+SUHNER RF connectors – QN 283
