摘　　要：用ADF4360-8和AD8343芯片作为变频核心器件,将70MHz信号转变为具有频率稳定、波形完整的11.4MHz中频信号。实验证明,该方案设计对接收机的稳定工作起到重要的作用,变频系统具有结构简单、操作方便、稳定性高等特点。ADF4360-8 and AD8343 chip are used as the core device to be frequency synthesis. The 70M signal is directly converted into a stable frequency, waveform integrity 11.4 M IF signal. Experiments show that the design of the plays an important role in the stability work of receiver. The frequency conversion system has some characteristics, such as simple structure, convenient operation, high stability and so on.
