Abstract

The invention provides a three-dimensional packaging terahertz radiation detector, which comprises a medium-extending hemispherical lens, a terahertz wave signal processing unit, an LTCC substrate, and a first intermediate frequency signal processing unit, wherein the terahertz wave signal processing unit comprises a gallium arsenide antenna and a gallium arsenide harmonic mixer; and the first intermediate frequency signal processing unit comprises an TCC substrate-based radio frequency passive balun receiving network and a first intermediate frequency signal processing circuit. Weak terahertz electromagnetic signals of atmospheric radiation and sub-millimeter wave local oscillator signals of space feed-in are converged on the gallium arsenide antenna via the lens, a first down-conversion processing is carried out via the gallium arsenide harmonic mixer, intermediate frequency differential signals are generated, the intermediate frequency differential signals are synthesized to intermediate frequency unbalanced signals via the balun receiving network, and the first intermediate frequency signal processing circuit converts the inputted intermediate frequency unbalanced signals into baseband signals processed by an A/D converter. The three-dimensional packaging terahertz radiation detector has the advantages of ultra wide frequency domain, three-dimensional packaging and multi-channel power synthesis.

Description

technical field [0001] The present invention relates to a terahertz radiation detector, in particular to a three-dimensional package terahertz radiation detector. Background technique [0002] The middle and upper atmosphere in the range of 20-120km mainly includes oxygen, carbon oxides, chlorine monoxide, water vapor and other useful gases that can reflect the physical, chemical and radiation conditions in the atmosphere. Through the detection, processing and analysis of related gas radiation electromagnetic waves, the relationship between the sun and the earth, global climate change and environmental change (including space environment and ground ecological environment) can be monitored in a timely and effective manner. According to the classification of the electromagnetic spectrum, electromagnetic waves covering the frequency range of 300MHz-300GHz are collectively referred to as microwaves, which include decimeter waves, centimeter waves, millimeter waves, and terahertz...
