HUBER+SUHNER’s line of lightning protection and EMP components are ideal for use in mobile communication systems, navigation systems, high-speed data transmission systems, radar, CATV, and video surveillance. This page provides an overview of the different products in this line and their ideal areas of use.
Gas Discharge Tube Protectors: Series 3401/3402
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 are performing excellent in NEMP applications as well. For specific applications, internally DC-blocked GDT protectors are also available.
Self-Extinguishing GDT Protectors: SEMPER Series
The design guarantees safe extinguishing of the GDT under high RF power or with additional DC components on the antenna line. By retrofitting standard GDTs with the SEMPER, existing GDT installations can be upgraded. The SEMPER technology is a real improvement to the standard gas tube technology and increases reliability and lifetime of GDT protectors.
True Broadband GDT Protectors: Series 3406
SlimLine GDT protectors feature high return loss in the frequency band between DC to 6 GHz. This design is best suited for Point to Point and WLAN equipment.
Hybrid/Low PIM/High Power GDT Protectors: Series 3409
This patented technology features low passive intermodulation at extremely high continuous and peak instantaneous power (up to 25 kW PIP).
Bias-T/DC Injectors with Integrated Lightning Protector: Series 3410
Bias-T's are used to feed-in or pick-off DC voltage into or from antenna feeder cables, provide the operating voltage for active electronics installed on the mast (mast head amplifiers, etc.)
Hybrid GDT Fine Protectors: Series 3403
For very sensitive DC powered receivers as used in GPS installations, the hybrid GDT fine protectors with integrated transient voltage suppressor diodes guarantee lowest residual pulse energy. HUBER+SUHNER fine protectors feature DC continuity.
Quarter-Wave Shorting Stub Protectors: Series 3400
HUBER+SUHNER quarter-wave shorting stub protectors perform best lightning parameters with excellent RF specifications within a limited bandwidth. A ratio of 4:1 between lowest and highest frequency of the frequency band is achievable by still meeting high return loss. For specific applications, internally DC-blocked quarter-wave shorting stub protectors are also available.
Filter Protectors: Series 3407
LC or LCL band pass filter technologies increase bandwidth to ratios larger than 4:1 in a compact mechanical design, making them an alternative to quarter-wave shorting stub protectors. LC or LCL filter protectors are internally DC-blocked.
Data Line Protectors: Series 3414
Our CAT 5 and CAT6 (Gigabit) data line protectors are Power Over Ethernet 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 centers).
Overvoltage protectors for applications up to 100 V DC, or 75 V AC based on varistor technology are available as single components.
High Voltage DC and DC/DC Blocks
Coaxial DC blocking components (DC blocks) with blocking voltage between 1 kV ; 4 kV and 15 kV are offered in a frequency range between 160 MHz and 3 GHz. High voltage DC blocks are used in railway applications but are also helpful in EMP protection applications to filter out the low frequency spectrum of the electromagnetic pulse.
Gas Discharge Tubes/Accessories
HUBER+SUHNER gas discharge tube protectors are normally delivered without gas tube sometimes called gas capsule. This allows the customer to select the appropriate GDT according to his or her application conditions, especially the maximum operation signal voltage amplitude.
