An engineer prefers DIFM receiver which is superior to instantaneous response rather than superheterodyne receiver which has a scan rate in normal wide band receiver designing. But DIFM receiver has weak point in sensitivity and continuous wave signal because of special environments. In this paper we propose the method which is certificated through simulation and prototype testing to improve sensitivity of DIFM receiver. And we analyze the important factors of DIFM receiver from our results.
