Abstract

The invention belongs to the technical field of strong electromagnetic pulse protection, and particularly relates to a radio frequency front-end electromagnetic pulse protection module which is suitable for satellite navigation positioning communication equipment. The protection module is used for carrying out strong electromagnetic pulse protection on the satellite navigation positioning communication equipment. The protection module comprises a first transient suppression circuit, a band elimination filter, a second transient suppression circuit and a shielding shell. Compared with the priorart, by using the protection module provided by the invention, problems of low bearing power and a low response speed of an existing radio frequency front-end protection module can be solved; and a power bearing capacity of the protection module is improved to a 10KW level, and the response time is reduced to be within 1ns so that effective protection of the radio frequency front end of the satellite navigation positioning communication equipment under an electromagnetic pulse radiation field is realized.

Description

technical field [0001] The invention belongs to the technical field of strong electromagnetic pulse protection, and in particular relates to a radio frequency front-end electromagnetic pulse protection module, which is suitable for satellite navigation and positioning communication equipment. Background technique [0002] At present, with the development of electromagnetic pulse technology, the RF front-end protection of various RF and microwave technology electronic information systems basically adopts a limiter module based on single-stage or multi-stage PIN diodes, which can protect the sensitive low-noise amplifier module of the RF front-end in digital It will not suffer physical damage under the high-intensity radiation field of 100 V / m. However, the electromagnetic pulse radiation field is as high as tens of KV / m, and the existing protection modules cannot ensure the safety of the RF front-end. [0003] Strong electromagnetic pulses can enter the interior of electroni...
