SPDs for coaxial lines

The task of the coaxial protection elements is to reliably protect the various types of radio communication technologies. They are particularly important when the technological devices are to process signals of a very low signal level (radio receivers, transceivers, cellular communication technologies, etc.). The circuits used here are adapted to the high sensitivity required for signals in the order of microvolts and therefore cannot withstand pulsed overvoltages with amplitudes many orders of magnitude higher. Expensive professional technology can then only be protected against destruction by well-designed surge protection devices.
