Abstract
To solve the system performance deteriorating problem caused by too lar ge variable range of signal power in receiver,this paper proposes an IF large d ynamic automatic gain control method with 70dB dynamic range based on IF signal detection voltage feedback and 2-stage AD8368 chip cascade structure.The analys is on closed loop control circuit proves that this method can solve the automati c control problem of signal gain within wide dynamic range,achieve fast,stable and automatic gain control,ensure high sensitivity of receiver under small sig nal conditions and improve the system of received sensitivity.关键词
