Gas Discharge Tube (GDT) Protectors

HUBER+SUHNER Gas Discharge Tube (GDT) Protectors utilize GDT technology, making them ideal for applications with RF and DC components on the antenna line. These electromagnetic pulse (EMP) protectors make the best of the traditional spark gap protection principle for general applications in electronics and adapt it to RF coaxial line applications. The protectors are generally designed as coaxial feed-through devices for 50Ω or 75Ω systems. They offer DC continuity for remote powering and broadband usage from DC up to 1GHz. HUBER+SUHNER GDT Protectors feature replaceable gas discharge tubes and easy maintenance.
