摘　　要：首先介绍了FMSCA无线寻呼的传统接收结构 ,重点提出超外差与零中频相结合以单片化实现FMSCA射频接收的拓朴结构 ,并给出了数学推导 。The traditional receptive topology of FM SCA radio paging has been firstly discussed. The topology combining super heterodyne and zero if for single chip implementation for FM SCA RF reception has been mainly proposed. The mathematics deduction is given,and it shows that the original signal can be effectively recovered through the topology.
