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.

•  Broadband
•  Available for application bands between 380 MHz and 18 GHz (N, SMA)
•  Best PIM performance
•  Highest current handling capability up to 100 kA max.

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.

HUBER+SUHNER gas discharge tube protectors are normally delivered without gas tube some times called gas capsule. This allows the customer to select the appropriate GDT in accordance with his application conditions, especially the maximum operation signal voltage amplitude.

•  Different or additional protectors need to be used for lightning protection.

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.

•  Impedance 50 or 75 Ω

3407 QUARTER-WAVE STUB TECHNOLOGY WITH INTEGRATED HIGH-PASS FILTER Family

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.

•  Residual voltage reduced by 80% compared to standard types of series 3400
•  Residual energy reduced up to factor 2000 (more than 99.9%) compared to the series 3400
•  DC-blocking on protected side of the device (galvanic isolation)
•  Available for applications from 70 MHz to 18 GHz (N, SMA)

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.

•  Residual voltage reduced by 40% compared to standard GDT protectors of series 3401/3402
•  Residual energy reduced by approx. 60% compared to the series 3401/3402

•  DC-blocking on protected side of the device (galvanic isolation)

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.
