Based on proven performance features, the new generation offers optimised external dimensions for installations where space is limited and is particularly robust and resistant to fire and strong heat. Find out more.
SATELLITE has played a critical role in determining how satellites will shape the future of our world. It unites aerospace thought leaders, entrepreneurs, executives, engineers, end-users and enthusiasts together for the largest and most important global connectivity technology event of the year.
HUBER+SUHNER QMA and QN connectors have a quick-lock coupling mechanism. QMA and QN are easy to mate and allow a high packaging density because no tools are needed.
HUBER+SUHNER QMA coaxial connectors are in accordance with QLF standard and available with 50 ohm impedance. The frequency range extends to 18 GHz, depending on the connector and cable type. However most of the QMA connectors are return loss optimised for frequencies up to 6 GHz. The interface is based on the SMA dimension but instead of a threaded coupling mechanism a new snap-lock mechanism is used. The QMA interface has a very similar performance to the SMA, but in addition it offers an easier, faster and safer coupling operation, helping customers to save significantly time during production. The packaging density of QMA is increased compared to SMA connectors thanks to the fact that no torque spanner is required to fasten the coupling nut. QMA is not intermateable with SMA. QMA connectors are also available as waterproof version (IP68) and are compatible with QLF standard.
QMA eXtreme is the advanced version of the waterproof QMA, combining the quick-lock mechanism and waterproof properties also in rough environmental conditions. The coupling mechanism is completely waterproof and not only the RF signal path, thus protecting the connector from corrosion in a salty atmosphere and from freezing in case of high humidity and low temperature.
HUBER+SUHNER QN coaxial connectors are available with 50 ohm 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 on 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.
Besides the outstanding characteristics of the quick-lock connector QN, this advanced version has some extra features. The coupling mechanism is completely waterproof and not only the RF signal path, thus protecting the complete connector from corrosion in a salty atmosphere and from freezing in case of high humidity and low temperatures. This extra features besides the excellent PIM performance (typical -162 dBc) and the optimum power performance (≈350 W by 2 GHz) makes this connector the ideal solution for antenna connections.
