  • Electrical surge protection circuits
    Patent number: 11764569
    Abstract: The present disclosure provides a circuit including a coaxial cable interface, a data module, a power module, a power signal transmission branch, and a data signal transmission branch. The data module may receive or output a data signal. The power module may receive or output a power signal. The power signal transmission branch may be electrically coupled between the coaxial cable interface and the power module, and may include an inductor that allows the power signal to pass. The data signal transmission branch may be electrically coupled between the coaxial cable interface and the data module, and may include a capacitor that allows the data signal to pass and a first electrical surge protection circuit. The first electrical surge protection circuit may release a surge current on the data signal transmission branch.
