Performance Features: 2.7 GHz High-Performance Gas Discharge Arrester (GDT G27): The operation of the gas discharge arresters involves diverting high currents from the inner conductor to the outer conductor and then to ground. The gas discharge cartridge is located between the inner and outer conductors. When the trigger voltage is exceeded, it ignites and short-circuits the overvoltage. Advantages of this series include very high discharge currents (up to 40 kA, 8/20 impulse), selectable trigger voltages ranging from 75 to 600 V, and a frequency-independent operating range up to 2.5 GHz. The gas discharge cartridge can be replaced afterward. 3.8 GHz High-Performance Gas Discharge Arrester (GDT G38): As an extension of the application spectrum of our high-performance gas discharge arresters for use in 5G applications, Telegärtner has developed a completely revised product family that promises very good return loss values at high frequencies up to 3.8 GHz. The operation of this product category is the same as that of the G27 arrester family. Here, too, trigger voltages can be selected from 75 to 600 V, and the gas cartridge can be replaced. The new development also provided the opportunity to expand the portfolio with new 4.3-10 and 2.2-5 surge arrester types. 6 GHz Compact Gas Discharge Arrester (GDT G6): This series operates on the same functional principle as the high-performance gas discharge arresters. It differs mainly in its more compact design and significantly expanded frequency range up to 6 GHz. This allows for use in WLAN applications with a transmission frequency of up to 5.8 GHz. The maximum discharge currents are slightly lower than those of the high-performance type, at 10 kA (8/20 impulse, single-use) and 5 kA (8/20 impulse, multiple-use), and the trigger voltage is set at 150-250 V. The surge arresters can be mounted using a single-hole installation.
