摘　　要：噪声是影响接收机灵敏度的重要因素之一。接收机引入的噪声越小,接收机灵敏度就越高。分析了接收机噪声,给出了射频前端噪声系数与接收机灵敏度的关系,论述了几种改善射频前端噪声系数的方法。Noise is one of the important factors to influence the receiver sensitivity.The smaller noise the receiver introduces,the better sensitivity it will have.This paper analyses the receiver noise,gives the relation between noise figure of radio frequency（RF）front-end and receiver sensitivity,discusses several methods to improve the noise figure of RF front-end in receiver.

关 键 词：接收机 灵敏度 射频前端 噪声系数
