Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The implementation of the protection module is divided into three types, such as figure 1 , figure 2 and image 3 shown. figure 1 In the protection module, only the primary high power limiting module 101 is included inside. This method can be used when the damage threshold of the electromagnetic pulse radiation field of the protected object is high (usually greater than 1000V / m). figure 2 Among them, the protection module includes a primary high power limiting module 101 , a control module 102 and a terminal low power limiting module 103 . This method can be used when the damage threshold of the electromagneti...

Abstract

The invention discloses a radio-frequency front-end electromagnetic pulse protection module, which comprises a primary high-power limiting module, wherein the primary high-power limiting module comprises multiple layers of coaxial protection membrane and a directional coupler; each layer of protection membrane is formed by protection chains, which encircle a circle center and are radially distributed on a coaxial printed circuit board and a circuit board; round magnetic rings sleeved on a coaxial inner conductor are arranged at two sides of each protection membrane; a nonlinear passive protection device used for pulse voltage suppression is distributed on each protection chain; the directional coupler is formed by a coupling line parallel to the coaxial inner conductor and a radio-frequency output joint fixed on a coaxial outer conductor. The radio-frequency front-end electromagnetic pulse protection module has 10Kw power-resistant ability, suppression degree of more than 60dB and subnanosecond response characteristic, and the problems of low bearing power, low suppression degree and slow response speed of the existing radio-frequency front-end protection module can be effectively solved.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a radio frequency front-end electromagnetic pulse protection module. Background technique [0002] At present, the RF front-end protection of various RF and microwave electronic information systems basically adopts a limiting module based on a single-stage or multi-stage PIN diode, which can protect the sensitive low-noise amplifier module of the RF front-end in a high-intensity radiation field of hundreds of V / m suffer no physical damage. 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. Specifically, there are the following problems: [0003] Low withstand power: The pulse power withstand capability of the protection module currently used does not exceed 1kW. Existing data show that the instantaneous coupling power of RF front-ends of various communication ...
