QN Straight Bulkhead Receptacle (jack) 1

HUBER+SUHNER QN coaxial connectors are available with 50 Ω impedance. The frequency range extends to 11 GHz, depending on the connector and cable type, however most of the QN connectors are return loss optimised for frequencies up to 6 GHz. The interface is based on the inner dimensions of the N connector, but, instead of a threaded coupling mechanism, a snap-lock mechanism is used.
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.

The newly developed HUBER+SUHNER XQN (eXtreme QN) is an advanced version of the standard QN connector. Besides the outstanding features of the QN connector, X-QN convinces with some extra advantages. Besides the RF signal path the coupling mechanism is completely waterproof thus protecting the connector from corrosion in a salty atmosphere and from freezing in case of high humidity in low temperatures. This extra features, additional to the excellent PIM performance (typically 162dBc) and the optimum power performance (~350 W by 2 GHz), makes this connector ideal as future-proof antenna connector.
