收音系列产品

SP7021F 内包含有高放、混频、本振、二级有源中频滤波器、中频限幅放大器、鉴频器、低频器、低频放大器、静噪电路以及相关静噪系统等，它具有单声道FM 收音机的全部功能。工作电源电压范围为1.8~6V，推荐值为3V。它适用单声道或立体声FM 收音机，尤其适用于低压微调谐系统。该电路采用 16 脚双列扁平封装。 ·由于中频频率很低，只有76kHz，因此中频滤波由内电路两级有源滤波器来实现，在外电路取消了中周变压器或陶瓷滤波器，减化了电路调整，缩小了体积。\n·输入回路不需要调谐，采用宽频带接收，通过改变本振调谐频率来选择电台信号。高频输入信号频率范围为1.5~110MHz。\n·电路内设有由混频、限幅中放、鉴频、本振（VCO）组成的频率锁相环电路，用来对中频频偏进行压缩，以满足广播信号的频带宽度。\n·电路内设有由相关静噪系统及静噪电路组成的降噪系统，可用于抑制无信号时、电源开关转换时以及接收弱信号时的噪声，提高信噪比。\n·;
