Overview
In the context of today's rapid development of network technology, base stations are an important part of communication networks, and their stability and reliability are directly related to the quality of communication services. In recent years, the problem of base station equipment encountering lightning strike accidents during operation has become increasingly prominent, especially the damage to the GPS receiving module, which has become one of the main factors affecting the normal operation of the base station. The loss of GPS signals not only limits the functions of the base station, but also brings bad experience to customers. Therefore, improving the lightning protection capabilities of the base station, especially protecting the GPS receiving module, has become an urgent problem that needs to be solved. To address this problem, Semiware has launched corresponding surge and electrostatic protection solutions, see the application block diagram.
