摘　　要：由于毫米波在技术上的优势,使得工作在毫米波频段的接收机具有体积小、重量轻、携带信息容量大和抗干扰能力强等特点,受到越来越广泛的应用。论述了毫米波接收机主要工作原理、研制过程及研制结果。该毫米波接收机主要包括毫米波功和器、电调衰减器、开关、毫米波LNA以及毫米波混频器等多个单元。通过电路优化设计,研制出的毫米波接收机增益为23.2 dB;噪声系数为11 dB;开关隔离度为42 dB;开关速度为3 ns。Millimeter-wave receiver has such features as small volume, light weight, great message capacity and strong anti-jamming capability due to the technical advantages of millimeter-wave. The paper introduces the theory of millimeter-wave receiver and its development process and result. This millimeter-wave receiver is composed of multiple units including millimeter-wave power synthesizer, attenuators, switch, millimeter-wave LNA and millimeter-wave mixer. The primary parameters of the millimeter-wave receiver include power gain of 23.2 dB, noise figure of 11 dB, switch isolation of 42 dB, and the speed of switches of 3 ns.
