Description

Technical field [0001] The invention belongs to the field of lightning protection devices, and specifically relates to a quarter-wavelength line radio frequency lightning protection device. Background technique [0002] The radio frequency lightning arrester is an overvoltage protection circuit used in radio frequency microwave systems (such as communication systems), which can protect valuable voltage-sensitive equipment in the system, such as low-noise amplifiers, mixers and receivers, from lightning or surges Damage. At the same time, it can provide protection for the power supply of the system. [0003] Radio frequency and microwave antenna feeder systems need to be installed in higher outdoor locations due to their work. They are prone to lightning strikes or induced lightning surge voltage. As long as these transient overvoltages and overcurrents enter the system, the receiving equipment will be burned immediately, causing the equipment to even Loss of personnel. With the d...
