Radio frequency receiver module based on electric wave environment testing

Abstract

The invention discloses a radio frequency receiver module based on electric wave environment testing, and belongs to the technical field of radio frequency receivers. The radio frequency receiver module comprises a barrel body; an end cover is arranged at left and right sides of the barrel body respectively; an input port is arranged at a central position of the end cover on the left; an output end of an A / D converter is electrically connected to an input end of a first digital gainer; and an output end of the first digital gainer is respectively and electrically connected to output ends of a power statistic module and a baseband filter. The output swing can be increased, the output linearity is improved, the noise of signal transmission is reduced, the stability of the signal transmission is guaranteed, and the signal transmission efficiency is improved; and thus, the stability of a testing result can be improved, and the resting requirement under an electric wave environment is met; by air vents on the end covers, the air inside the barrel body can be circulated, so the heat dissipation performance is improved and the service life of the radio frequency receiver is improved; and a water absorption layer can absorb water vapor in the barrel body, so that the occurrence of an unexpected condition is avoided.

Description

technical field [0001] The invention relates to the technical field of radio frequency receivers, in particular to a radio frequency receiver module based on radio wave environment testing. Background technique [0002] Radio waves are also called electromagnetic waves. Refers to the periodically changing electromagnetic field propagating in space. Radio waves and light, X-rays, gamma rays, etc. are all electromagnetic waves with different wavelengths. The radio wave is affected by the medium and the interface of the medium, resulting in reflection, scattering, refraction, diffraction and absorption, which changes the characteristic parameters of the radio wave such as amplitude, phase, polarization, and propagation direction. Radio frequency is referred to as RF radio frequency is radio frequency current, which is an abbreviation of high-frequency alternating electromagnetic waves. The alternating current that changes less than 1,000 times per second is called low-freque...
