Abstract

The invention relates to the technical field of interference protection and discloses a high-power capacity and high-power microwave protection device. The device comprises an input interface, an output interface, a multi-stage steady-state filter circuit and a three-stage transient bleeder circuit, wherein the multi-stage steady-state filter circuit is composed of a plurality of steady-state filter circuits connected in series, two ends of the multi-stage steady-state filter circuit are connected with the input interface and the output interface through microstrip lines respectively, and thethree-stage transient bleeder circuit is connected in parallel with the steady-state filter circuit through an impedance matching line. The device is large in rated power capacity, small in insertionloss, high in response speed, high in universality, convenient to install and maintain, capable of effectively preventing high-power microwaves from damaging electronic equipment, and capable of beingapplied to high-power microwave protection of short-wave, ultra-short-wave and other receiving and transmitting integrated communication systems.

Description

technical field [0001] The invention relates to the technical field of interference protection, in particular to a high-power microwave protection device with high power capacity. Background technique [0002] The electromagnetic killing effect of high power microwave weapons on electronic equipment, communication networks and weapon systems in conventional warfare is very obvious. With breakthroughs in key technologies such as battery technology, high-power microwave sources, and radiation antennas, the high-power microwave energy radiated by high-power microwave weapons can reach 1GW-10GW, and the pulse rise time can reach below 1ns, which is especially important for various electronic devices. It is the high-power microwave protection capability of the communication system that poses a severe test, and improving the high-power microwave protection capability of the communication system has become an urgent task. [0003] Shortwave / ultrashort wave communication is the mai...
