InnoTrans 2018

InnoTrans is the leading international trade fair for transport technology and takes places every two years in Berlin.
A unique feature of InnoTrans is its outdoor and track display area, where everything from tank wagons to high-speed trains are displayed on 3 500 metres of track.

Transmission

Transmission
The transmission cable must be robust and mobile and is therefore strengthened with specially developed reinforcements. At the same time, the microwaves must be transferred from the generator to the antenna in the applicator with minimal energy losses. The cables are therefore strengthened with special reinforcements to make them crush-resistant. The materials used in the cable are also selected to meet the requirements for medical use, above all for sterilisation. Properties such as coolability and the diameter of the transmission cable likewise play a major role in the cable selection process.

Low-loss transmission cables
A low-loss microwave cable is the key component in a transmission cable. In addition to minimal losses in the cable, flexibility, haptics and weight are other important factors. Since the cables also come into contact with the patient, they should also not become hot if possible. HUBER+SUHNER Sucoflex cables are used for this application.

Cable connectors
The connection of the transmission cable to the generator must ensure that power can be transmitted while also withstanding a high number of connection cycles with the generator. The connector must be easy to use while also ensuring a high level of connection reliability.

Interface connectors
The connection between the transmission cable and applicator is often located in a special unit mounted on the operating table. Easy, fast handling, even when using the applicator with medical gloves, is a central requirement for the ergonomic properties of this radio frequency connector, in addition to its electrical properties.

Hybrid cable assemblies
In addition to microwave transmission, other connections may be integrated in the transmission cable, such as signal cables for a wide range of sensors. HUBER+SUHNER works with customers to develop complete cable assemblies with hybrid connectors which are both compact and can also withstand high mechanical forces .

Recommended Products

Blind mate connectors (BMA)

HUBER+SUHNER BMA offers a range of blind mate connectors for floating configurations with axial or radial misalignment up to 18 GHz.

BMA series

BMA series

HUBER+SUHNER BMA blind mate connectors open up special dimensions in microwave applications up to 18 GHz. HUBER+SUHNER offers a range of connectors for fixed as well as floating configurations with any axial or radial misalignment taken out by the outer contact of the jacks. The BMA series presents an outstanding range of products featuring high reliability and ease of assembly. HUBER+SUHNER BMA connectors are intermateable with the OSP connector series.

Formable microwave cable assemblies

In applications with limited space, formstable and pre-bent cables and assemblies make life easier by facilitating quick and convenient installation with stable and repeatable quality. They come with either a tubular outer conductor, ideal for customised configurations, or a tin soaked braid, perfect for individual hand form routing.

Thanks to its 100% solid outer conductor, the products stand out from commonly braided cables by providing superior RF shielding, outstanding VSWR and PIM performance.

Sucoform assemblies

Sucoform assemblies

Sucoform microwave coaxial cables offer distinct mechanical advantages over semi-rigid cables. They are based on the same design as the standard PTFE insulated semi-rigid cables, but have a tin-soaked copper braid for the outer conductor, giving them outstanding hand-formability. These cables combine the excellent characteristics of semi-rigid cables with those of flexible coaxial cables. Thanks to their small bending radii, they allow space saving routing and packaging.

Microwave cable assemblies

HUBER+SUHNER SUCOFLEX flexible microwave cable assemblies offer superior electrical and mechanical performance for static and dynamic applications. This series is a high-end product designed to provide optimal performance up to 50 GHz, where stringent electrical requirements, in particular electrical stability and low loss, are important. Ideally suited for test and measurement applications and defense systems. Additional lightweight high-end versions are designed to meet the stringent needs of space flights systems (i.e. satellites) and aerospace systems (aircrafts, helicopters, missiles), which are subject to extremely severe operating conditions. SUCOFLEX is only available as assembly.

SUCOFLEX 100

SUCOFLEX 100

The SUCOFLEX 100 series flexible microwave cable assemblies offer superior electrical and mechanical performance for static and dynamic applications. This series is a high-end product designed to provide optimal performance up to 50 GHz, where stringent electrical requirements – in particular stability and low loss – are important. Their mechanical and climate resistance properties surpass those of standard flexible cables. 

Quick lock connectors (QMA/QN)

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.

QMA

QMA

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.

QN

QN

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.
