coaxial connectors are according to QLF standard and are available with 50 Ω 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 (IP 68) and are compatible with QLF standard.
(the 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 (IP68) 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.
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.
HUBER+SUHNER 50 Ω BNC
is still a popular connector serie, featuring a two stud bayonet coupling mechanism, which is particulary useful for grequently coupled and uncoupled RF connections with frequencies up to 4 GHz. 50 Ω BNC connectors and «Real» 75 Ω BNC
connectors are suitable for applications up to 3 GHz, contrary to the conventional 75 Ω BNC connector types, which are applicable up to 1 GHz only. With the HUBER+SUHNER® full crimp technique, they can be assembled quick and easy to all convenient cable types.
Thanks to good electrical properties they are suitable for different applications, such as broadcast, telecommunication, etc. Mechanically they are mateable with all conventional BNC connectors (50Ω and 75Ω).
HUBER+SUHNER 50 Ω TNC
connectors are threaded RF connectors applicable from DC up to 11 GHz. The threaded coupling mechanism improves control over the interface dimensions and allows them to be used under a higher environmental load than BNC, especially under a high vibration load. Within the internationally standardized TNC mating face dimensions a perfect 75 Ω
characteristic impedance cannot be realized. However, at frequencies up to 1 GHz the small impedance deviation is negligible for practical applications. The threaded coupling mechanism allows them to be used under higher en-vironmental load than BNC.
50 Ω TNC connectors and 75 Ω TNC connectors are intermateable without restrictions.
twin connectors are two pin bayonet coupled (same bayonet locking mechanism as BNC) connectors for use with balanced twin-conductor cables with 75 Ω to 130 Ω impedance. They have polarized contacts and are not intermateable with BNC.
The HUBER+SUHNER BNO twin connectors are suitable for applications up to 200 MHz (i.e. computer networks and process control).
triaxial connectors are RF connectors with a bayonet coupling mechanism and three concentric contacts (inner conductor, inner screen and outer screen) for triaxial cables.
HUBER+SUHNER BNT connectors are intermateable with BNC connectors, but the inner conductor and outer screen are connected only. BNT connectors are suitable for applications up to 3 GHz (inner coaxial line).
(Safe High Voltage) connectors provide more secure handling: center contacts are well recessed to prevent shock hazards in unmated condition. All inner contacts are fully captivated and will withstand axial forces of 100 N minimum. When mating a connector pair the outer conductor contact is made prior to the inner conductor contacts.
SHV connectors are suitable for all high voltage applications up to 5 kV DC or 3.5 kV rms. These connectors are typically used in nuclear instruments or test and measurement equipment. Voltages are valid for both, the mated and the unmated condition.
connectors are coaxial miniature high voltage (MHV = Miniature High Voltage) connectors with 5 kV rms test voltage (mated pairs). The MHV connectors have a working voltage up to 1.6 kV rms in mated condition and are suitable for applications up to 300 MHz. MHV connectors are of similar design to BNC connectors but the insulators protrude over the outer contacts to give a degree of contact-voltage proof when unmated. However, if a high degree of protection in the unmated condition is required, use of series SHV is recommended.
connectors offer very low PIM performance together with weight and compactness advantages. A key feature of this connector is the separation of the electrical and mechanical plane, which results in a lower coupling torque and the possibility of offering the connector with screw, hand-screw and quick-lock design, thus simplifying the installation effort and offering for all mechanisms a very high and reliable electrical performance independently from the torque applied.
connectors are medium size RF connectors with two-stud bayonet mechanism which allows quick and easy coupling and de-coupling. The C connectors provide 50 Ω impedance and the frequency range (connector interface) is specified for applications up to 11 GHz.
connectors are available with 50 Ω and 75 Ω impedance. The frequency range extends to 18 GHz, depending on the connector and cable type. The screw-type coupling mechanism provides a sturdy and reliable connection.

Cable entries: clamp, crimp and solder types available, as well as HUBER+SUHNER QUICK-FIT for corrugated copper tube cables.
do not have defined impedance. They are intended for applications up to 200 MHz where mechanically robust connectors are required. They are mateable with 4 mm banana plugs.
connectors are mechanically very rugged coaxial connectors with screw lock. They have a characteristic impedance of 50 Ω and are applicable with excellent electrical properties up to 7.5 GHz.Transmission of medium to high power in transmitting stations and low loss transmission of received signals such as in mobile phone base stations are typical applications. For these purposes lowintermodulation product and waterproof types are also available.
According UL FCC (part 15.203) regulations, wireless radio equipment with removable antenna must not have a standardized interface. This to avoid the connection of antenna equipment which is not WLAN approved. An established solution are the so called reverse polarity connectors
. That means, the male connector is fitted with female centre contact and insulator, whereas the female side is fitted with male centre contact and insulator. For identification of reverse connectors the letter R (for reverse) is used in the type description. Example: 11_TNC-R50-3-42.
Hermetic is greek. It means impenetrable, barred, air and watertight, etc.
The heart of a «hermetic» connector is a glass-seal. This is a center contact as well as a metal ring, which are separated and isolated by melted glass. The glass-seal is soldered into the connector body and is sealing the connector internally.
Years of experience in development and production, as well as special equipment for soldering and testing the leak rate are reasons why HUBER+SUHNER is a competent and reliable manufacturer of hermetically sealed RF connectors.
