Lightning & EMP Protectors

Four decades of experience in developing and manufacturing coaxial lightning EMP and NEMP protectors are the foundation of the current our supplier HUBER+SUHNER`s RF protection portfolio.

The products are designed to meet the stringent requirements of the RF/microwave, telecommunications and wireless industry and cover civil, security and defense applications. An extensive high-voltage impulse laboratory is established to verify their designs in accordance with the valid international lightning, surge and NEMP standards.

Important inventions are covered by world – wide patents.
Data line protectors

HUBER+SUHNER data line protectors are designed to protect sensitive high speed data networks up to CAT6 in channel class E. Some data line protectors are suitable for use with Power over Ethernet (PoE) in accordance with IEEE 802.3at.

 

Our CAT5 and CAT6 (Gigabit) data line protectors are Power over Ethernet (PoE) compatible and available as IP68 rated robust components for outdoor applications (i.e. backhaul microwave links) or in IP20 specified housings for indoor installations (i.e. data processing centres).

 

Gas discharge tube EMP protectors

HUBER+SUHNER gas discharge tube (GDT) technology based EMP 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.

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.

 

3402 gas discharge tube protectors up to 3 GHz

HUBER+SUHNER gas discharge tube protectors make the best of the traditional spark gap protection principle for general applications in electronics and are perfectly suited to RF coaxial line applications. Specially designed gas discharge tubes are a key feature. The available product range of GDT’s enables selection in accordance with RF transmission power and optimum protection performance. A very important feature of GDT protectors is the option of DC/AC power outdoor equipment via coaxial cable. Series 3402 products can be used broadband from DC to 2.5 GHz respectively up to 3 GHz for platform 3000. They are generally designed as coaxial feed-throughs which allow the customer to build up a protected area in accordance with the recommended and well-proven protection zone principle of IEC 62305. HUBER+SUHNER GDT protectors are designed such that the gas discharge tubes can be easily exchanged for new operation conditions or replaced in the case of a necessary service.

 

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. slimlin 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

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. They have been established as a worldwide industry standard by HUBER+SUHNER as the original manufacturer. The products are maintenance-free and feature the best protection performance with both the highest surge current handling capability and the lowest residual pulse amplitude. Also, their RF performance is superior to other designs, including passive intermodulation. HUBER+SUHNER lightning EMP protectors series 3400 offer a large variety of products and can be adapted to any application. Besides connectorisation and mounting principle, the frequency range has to be selected properly due to their generally limited bandwidth.

 

3407 quarter-wave stub technology with integrated high-pass filter

HUBER+SUHNER quarter-wave lightning protectors with integrated high-pass filter feature an added useful RF component to the proven premium standard quarter-wave protector design. Thus, they can offer an essentially improved protection performance.

High voltage DC- and DC/DC blocks

The HUBER+SUHNER DC Block product line includes DC blocks (inner conductor disconnected) and DC-DC blocks (inner and outer conductor disconnected) for galvanic isolation up to 15 kV. They block high-amplitude and low frequency surge voltages e.g. occurring during regular electric railway operation along railway lines. They provide sufficient safety even in the event of the overhead high voltage lines falling to the ground.
