The CXP Series has been designed to protect radio-base communications systems from lightning and electrical transients. This device is a DC blocked protector not to be used where transmitter combining is performed.

The CXP Series is designed to protect terminals connected to coaxial cables against transient overvoltages due to lightning strikes. The CXP Series is a combination of Gas Tubes and clamping diodes which allows a high discharge current with a low residual voltage and low insertion losses.
