Miniaturization electromagnetic sensor

Abstract

The invention relates to a miniaturization electromagnetic sensor comprising a frequency synthesizer, and a broadband antenna, a radio frequency front module, an intermediate frequency processing module and an output interface connected in order, wherein the broadband antenna is used for sensing space electromagnetic signals; the radio frequency front module comprises a radio frequency switch array and a plurality of radio frequency channels integrated on a same chip through a bonding technology; the radio frequency switch array respectively connects space electromagnetic signals of differentfrequencies into different radio frequency channels; a mixer is arranged in each radio frequency channel; the mixer can down-convert the space electromagnetic signal in the radio frequency channel into an intermediate frequency signal of a specific frequency; the intermediate frequency processing module can down-convert the intermediate frequency signal at the specific frequency into a base-band digital signal, thus outputting feature information of the space electromagnetic signals. A conventional electromagnetic signal measuring device is large in size, hard to move, and cannot realize filedelectromagnetic compatibility measurement and assessment for work equipment, especially aircraft equipment; the miniaturization electromagnetic sensor can solve said problems.

Description

technical field [0001] The invention relates to the technical field of electromagnetic sensors, in particular to a miniaturized electromagnetic sensor. Background technique [0002] Electromagnetic interference refers to the interference of electronic equipment and systems by strong electrical interference or external electromagnetic signals, resulting in a decrease in the performance of the equipment or failure to work normally. When the equipment is working, due to the different environments, it may be affected by the surrounding interference sources, resulting in abnormal operation of the equipment, which has caused great harm in the military and civilian fields. [0003] Although our country or other countries have established strict inspection norms and standards when each type of electronic equipment leaves the factory, for example, many electromagnetic compatibility microwave anechoic chambers have been established to test the reliability of electronic equipment throu...
