HUBER SUHNER QN User Manual
SERIES QN, COAXIAL CONNECTORS
DESCRIPTION
HUBER+SUHNER QN coaxial connectors are available with 50 8 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 GH z. The i nterface is based on the inner dimensions of the N connector, but, instead of a threaded coupling mechanism,
a new snap-lock mechanism is used.
The QN interface has a very similar performance to the
N, but in addition it offers an easier, faster and saver
couplingoperation, helpingthe customers to savesignificantly 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 TNC-size flanges can be used at QN connectors.
