Abstract

The invention is applicable to the technical fields of terahertz security inspection, substance detection, remote sensing, medical diagnosis and the like, and provides a radiometer front end structureand terminal equipment. The structure comprises a metal box body, a two-stage low noise amplifier chip, a detector chip, a quartz probe and a video amplifier, wherein a groove is formed in the upperside of the metal box body, a plurality of bosses are arranged in the groove, and the bosses are used for positioning the chips; the two-stage low noise amplifier chip and the detector chip are sequentially arranged on the corresponding bosses; the quartz probe is arranged in the groove of the metal box body, is located on the left side of the boss corresponding to the two-stage low noise amplifier chip, and is used for receiving signals radiated by objects; and the video amplifier is arranged in the groove of the metal box body and located on the right side of the boss corresponding to the detector chip. The adjacent devices are in electrical connection with each other, so that the volume of each circuit can be significantly reduced, the advantages of high integration level and fully-automatic assembly can be realized, the assembly difficulty can be reduced, and the engineering manufacture and batch production can be achieved.

Description

technical field [0001] The invention belongs to the technical fields of terahertz security inspection, material detection, remote sensing and medical diagnosis, and in particular relates to a radiometer front-end structure and terminal equipment. Background technique [0002] A radiometer is a high-sensitivity receiver used to measure the thermal radiation of objects and is the main tool for passive microwave remote sensing. At present, microwave radiometers based on ground-based (including ground and ship-borne platforms), space-based (including aircraft, missile, balloon platforms), satellite-based (including satellite, spacecraft, space shuttle platforms) and other carrier platforms have been developed rapidly. The radiometer has also developed from the meter-wave radiometer to the current millimeter-wave, sub-millimeter-wave and even terahertz radiometers. Terahertz can pass through non-metallic and non-polar materials with little attenuation, and realize terahertz imag...
