Integrated high-sensitivity millimeter wave receiver for millimeter wave array imaging system

Abstract

The invention provides an integrated high-sensitivity millimeter wave receiver for a millimeter wave array imaging system, which comprises a plate body with a hole body, an integrated RF circuit fixed on one side of the plate body, a power supply circuit fixed on the other side of the plate body, and two packaging cover bodies; the integrated RF circuit further comprises a plane micro strip slot antenna used to receive millimeter wave, a low-noise amplifier used to amplify the accessed millimeter wave, and a mixed and integrated diode detector used to convert the amplified millimeter wave into low-frequency voltage signals which are in direct proportion to the power; the power supply circuit is connected with the integrated RF circuit through the hole body, and is used to supply power to the RF circuit; and the two packaging cover bodies are used to clamp the plate body for packaging. The compact structure can effectively overcome large size, poor stability and other defects, greatly reduces the size and the weight of the millimeter wave receiver, improves the performance, the quality and the reliability of the complete machine, and is applicable to mass production, so as to meet the needs of the array millimeter wave imaging system.
