Strong-electromagnetic pulse protection device of ultra-short wave communication frequency range

Abstract

The invention provides a strong-electromagnetic pulse protection device of an ultra-short wave communication frequency range. The device is characterized by comprising a gas discharge pipe, a micro-strip low-pass filter and a lumped parameter band-pass filter which are encapsulated in a metal box, wherein an input end and an output end are arranged at two ends of the metal box; the input end is connected with one end of the gas discharge pipe and the input end of the micro-strip low-pass filter respectively; the other end of the gas discharge pipe is grounded; the output end of the micro-strip low-pass filter is connected with the input end of the lumped parameter band-pass filter; the output end of the lumped parameter band-pass filter is connected with the output end of the metal box; and the input end and the output end at the two ends of the metal box are coaxial ports. By adoption of two-stage protection circuits of the gas discharge pipe and the micro-strip low-pass filter, the strong-electromagnetic pulse protection device of the ultra-short wave communication frequency range can more reliably filter a strong-electromagnetic pulse having a shorter rising front edge.

Description

technical field [0001] The invention belongs to the technical field of strong electromagnetic pulse protection, and in particular relates to a composite strong electromagnetic pulse protection device suitable for ultrashort wave communication equipment, which can be used for strong electronic pulse protection of various ultrashort wave frequency band communication electronic equipment. Background technique [0002] With the development of electromagnetic pulse technology, the electromagnetic pulse radiation field strength reaches hundreds of kV / m, and the pulse rise time is less than 1ns, which is more and more harmful to communication electronic equipment. The electromagnetic pulse induced by strong electromagnetic pulse on communication and other equipment Voltage and current can instantly breakdown or burn communication equipment, so it is urgent to provide strong electromagnetic pulse protection for communication electronic equipment.

Problems solved by technology

However, the response time of the traditional receiving channel lightning protection module is long, and the protection effect on the strong electromagnetic pulse at the ns level rising front is not obvious. At present, there is no strong electromagnetic pulse protection device specially used for ultrashort wave frequency band communication receivers
