RF ATEX-certified components

Communication in explosive (Ex) environments is becoming increasingly critical. Concepts of the Internet of Things (IoT) are applied to increase productivity and provide a higher degree of automation. This is especially important since many oil and gas installations are remote and flexibility is often limited due to long distances and high transportation costs.

HUBER+SUHNER provides a large portfolio in RF connectors and adaptors, cables, antennas and lightning protectors. It offers a rich history and experience in designing and manufacturing RF components, which allows a high flexibility for customer specific products.

From the portfolio, there are also RF components with ATEX and IEC-Ex certification available. This portfolio includes entry devices and lightning protectors for Zones 1 and 21. HUBER+SUHNER production locations are certified for production of ATEX-components.

HUBER+SUHNER’s portfolio provides all products required for the analog RF-path between the access point and the antenna, with excellent RF performance and the highest quality standards.

Ex RF surge protective devices

HUBER+SUHNER Ex surge protective devices are approved for use in potentially explosive atmosphere or hazardous locations and areas of Zone 2 (gas) and Zone 22 (dust) and provide reliable prevention against dangerous overvoltage surges on coaxial lines. This includes all kinds of interference, e.g. resistive, magnetic field and electric field coupling, caused by lightning strikes, switching and other natural or manmade electrical effects. This way, the operator of active equipment is not only protected from financial losses caused by the need of replacing the equipment, but also avoids downtime of the system after a possible event. This is specifically important in environment where access to equipment is difficult, dangerous and expensive, as on an oil platform for instance.

Ex entry devices for coaxial RF lines

HUBER+SUHNER Ex entry devices are approved for use in in potentially explosive atmosphere or hazardous locations and areas of Zone 1 (gas) and Zone 21 (dust) and for coaxial cabling/interconnection with Ex-d enclosures. These products are of specific interest where an active access point is placed within an Ex certified enclosure, which needs to be connected with an antenna (Ex-i or in an housing). Different cable connectors in combination with the appropriate cable allow maximum flexibility in routing cables at highest possible performance and lowest possible losses.

Gas discharge tube (GDT) protectors

HUBER+SUHNER gas discharge tube (GDT) technology based protectors are generally designed as coaxial feed-through devices for 50 or 75 ohm systems. GDT technology based protectors feature DC/AC continuity for remote powering and large bandwidth.

3401/3402 gas discharge tube protectors

Standard versions for applications with RF and DC components on the antenna line. The standard GDT lightning / EMP protectors feature DC continuity and large bandwidth. Most HUBER+SUHNER GDT protector designs also offer excellent performance in NEMP applications. For specific applications internally DC-blocked GDT protectors are also available.

3403 fine protector hybrid technology

HUBER+SUHNER fine protectors are a very special group of lightning EMP protectors which provide a very high degree of protection, especially for applications with DC powering via coaxial cable. They offer an extremely effective surge pulse reduction, which makes them suitable to protect even very sensitive microelectronic circuits, e.g. GPS timing systems for CDMA mobile communication systems.

3404 miniature gas discharge tube (GDT) technology

HUBER+SUHNER miniature gas discharge tube protectors are designed to protect against NEMP (Nuclear Electromagnetic Pulse) and other electromagnetic interferences. The special design guarantees an excellent dynamic protection performance. It includes a fixed integrated gas discharge tube. Miniature GDT protectors have a bulkhead feed-through design and can be easily installed instead of a standard waterproof bulkhead coaxial connector to harden existing equipment. Different or additional protectors need to be applied for lightning protection.

3406 true broadband GDT protectors, slim line gas discharge tube (GDT) technology

HUBER+SUHNER 3406 slimline protectors provide surge protection for any electronic equipment connected to coaxial lines up to 6 GHz. The gas discharge tube protection principle supports simultaneous transmission of RF, data and DC. The gas discharge tubes are fix integrated. The protectors can handle any induced surge signals but partial lightning current up to the specified current handling capability only. For higher lightning current handling refer to our gas discharge tube (GDT) protector series 3401 and 3402. Multi-carrier applications with high RF peak power and special passive intermodulation requirements are covered by series 3409.

3408 gas discharge tube (GDT) technology with integrated high-pass filter

HUBER+SUHNER gas discharge tube (GDT) protectors with integrated high-pass filter feature an added useful RF component to the proven standard GDT protectors. Thus, they offer a much better protection performance. The design allows a DC injection facility to be integrated as well. Gas discharge tubes can be easily exchanged for new operation conditions or replaced in the case of a necessary service.

3409 high-power/low-IM gas discharge tube (GDT) hybrid technology

HUBER+SUHNER series 3409 high-power gas discharge tube (GDT) protectors are a new generation of ultimate GDT protectors – suitable to meet the demanding high RF performance and protection requirements of future mobile communications transceivers with DC powering of outdoor equipment. The customer is freed from any RF power and IM performance considerations. Thus the protectors are especially suitable for multicarrier systems. The availability of this kind of GDT protectors concerning frequency range is not limited by the gas discharge tube (as it is the case with standard GDT protectors which are limited to applications below about 3 GHz). In addition, the protection performance is superior to existing standard GDT protectors.

Semper – self-extinguishing gas discharge tube (GDT) protector

The patented Semper concept enhances the safety and reliability of the well-known and proven gas discharge tube (GDT) protector principle impressively. It eliminates the risk of gas discharge tube "hold on" due to DC line powering or high powered RF signals, which will render the system inoperable and can destroy the discharge tube. HUBER+SUHNER offers a unique concept of self-extinguishing GDT protectors. The unique and patented Semper solution is realised as a simple unit which enables the use of the comprehensive range of HUBER+SUHNER GDT protectors with a replaceable GDT. An easy retrofit of existing GDT protectors is possible or available as complete Semper protectors in a variety of configurations. Whereas many applications generally benefit from the enhanced safety and reliability that the Semper concept offers, applications using DC line power for remote signal amplification and processing and those using high RF power will find self-extinguishing lightning EMP protectors of specific interest.

Quarter-wave shorting stub protectors

HUBER+SUHNER protectors based on quarter-wave technology feature excellent protection performance with very good RF specification. For specific applications protectors with internal DC-block are available.

3400 quarter-wave shorting stub technology protector

HUBER+SUHNER quarter-wave lightning EMP protectors offer the best lightning protection available in the market, as they form a short for surge signals basically.
