ARRESTER(LIGHTNING PROTECTOR)


 

GAS DISCHARGE TUBE TYPE

Gas discharge tube arresters make the best of the traditional spark gap protection principle for general applications in electronics and adapt it perfectly to RF coaxial line applications. At their heart are specially designed gas discharge tubes. The available product range of gas discharge tubes. The available product range of gas discharge tubes enables a selection according to the RF transmission power with an optimum protection performance. A very important feature of the GDT protectors is the possibility to DC/AC power outdoor equipment via coaxial cable. They are generally designed as coaxial feed-throughs which allow the customer to build up a protected area according to the recommended and well-proven protection zone of IEC62305.

QUARTER WAVE SHORT STUB TYPE

This technology is based on a quarter-wave transformation line. The coaxial shorting stub applied for this purpose is shor-circuited at its end, and its length is matched to the mid-band frequency of the operation band. It thereby forms a bandpass filter. Its bandwidth can be adjusted up to ±50% of the center frequency. Since lightning interferences have a low frequency spectrum as described above, the shorting stub acts as a short circuit, donducting the current to the ground.
