F Surge Suppressors 75 Ω

The Telegärtner attenuators are used to reduce rf signal levels. Designed for use up to 6 GHz, these attenuators guarantee a precise signal attenuation of 3, 6, 10 or 20 dB, depending on the type used. Typical applications are in the field of test and measurement, as well as for antenna lines, where the emission must be set at defined levels ( eg. mobile communications, WLan etc. ).

The 2.7 GHz F Series gas discharge tube type suppressor functions by diverting high voltage surges from the centre conductor via the outer conductor to earth. When a defined voltage on the centre conductor of the coaxial line is exceeded, the gas discharge tube positioned between the inner and outer conductor fires and shorts them. Advantages of this type of suppressor are the high discharge currents (up to 20 kA, 8/20 Impulse), availability with a variety of spark-over voltages from 75 V to 1000 V, and broad-band suitability (d.c. to 2.7 GHz). The gas discharge tube can be replaced during service checks.
