Abstract
A device and method are disclosed for protecting a wireless communication system from impulse surges occurring in the system under the impact of lightning discharges. The device includes a high frequency line, and a first decoupling filter formed as a λ/4 section and a gas arrestor, sequentially connected to the high frequency line, in which the gas arrestor is connected between the first decoupling filter and the ground. A low frequency line and a second decoupling filter are connected in series between an output terminal, through which a signal flows into a circuit, and a contact point between the first decoupling filter and the gas arrestor. The low frequency line includes a low voltage limiter and a low pass filter. A T-shaped high pass filer is connected to the high frequency line.
