A radio frequency lightning protection device and method

Abstract

The embodiment of the present invention discloses a radio frequency lightning protection device, comprising: a cylinder, an insulating medium, the cylinder includes a connection part, a stop part and a base body, the stop part and the connection part are arranged on the base body, The blocking part is used to connect with the inner conductor of the radio frequency coaxial line and the conductor on one side of the circuit board; the connecting part is used to electrically connect with the grounding device on the other side of the circuit board to realize The column is grounded; wherein, the insulating medium covers the peripheral side of the base body, and the distance between the position where the connection part is connected to the grounding device and the stop part is (1 / 4+N / 2) wavelength, N is an integer. The radio frequency lightning protection device adopted in the embodiment of the present invention is small in size, which is beneficial to miniaturized design.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a radio frequency lightning protection device and method. Background technique [0002] Due to work needs, RF microwave systems are mostly installed outdoors at higher geographical locations, and are prone to lightning strikes or induced lightning surge voltages. As long as these instantaneous overvoltages and overcurrents enter the system, the receiving equipment will be burned immediately, causing equipment and even personnel harm. With the development of modern communication, the radio frequency lightning protection of communication equipment has attracted more and more attention. [0003] In the process of realizing the present invention, the inventor finds that the prior art has at least the following disadvantages: [0004] The RF front-end modules of communication base station products are connected by RF cable antennas. Generally, RF cables need to pass...

Problems solved by technology

[0004] The RF front-end modules of communication base station products are connected by RF cable antennas. Generally, RF cables need to pass through the cavity duplexer / filter module first. Since the cavity duplexer / filter itself is a DC blocking module, it can solve the problem of lightning protection. However, as the miniaturization requirements of base station products become increasingly urgent, cavity duplexers / filters are too large to meet the miniaturization requirements.
