Communication electronics refer to the circuit modules, control boards, signal processing units and transmission components used in communication equipment such as base stations, optical communication modules, routers, wireless transceivers, communication terminals and industrial communication gateways. It adapts to complex environments such as high temperature, low temperature, strong electromagnetic interference, high humidity and long-term continuous operation, and is the core hardware support for ensuring stable signal transmission, high-speed data communication, anti-interference and long-term reliability of communication systems.
