摘　　要：以被动式毫米波成像为应用背景,研制了一种频带宽4GHz、中心频率25GHz的集成直接检波式接收机的原理样机.介绍了接收机的工作原理,设计、制作、测试了原理样机各个功能模块并对整个系统进行了测试.A MMIC direct detection receiver in principle-model version with a central frequency of 25 GHz and a 4 GHz bandwidth was developed on the background of passive millimeter imaging systems. The operation principle of the receiver was describesd. Each part of the receiver was designed, manufactured, and measured individually and then the complete receiver was tested.

关 键 词：毫米波接收机 直接检波 被动式毫米波成像
