Abstract:
For wideband RF systems, the integration of the module determines the size of the module, and the size of the module affects its use range. Similarly, the hardware cost of the module is also an important indicator that needs to be considered in this design. In this paper, an integrated local oscillator is implemented by selecting a low-cost frequency hopping source device in combination with STM32. Combined with the dual-channel frequency conversion module, it can effectively reduce the module volume and improve the module integration, while reducing the cost of the local vibration source by about 50%, thereby effectively reducing the cost of the component. By making the frequency hopping core board separately, the assembly difficulty of the components is reduced, the production efficiency is improved, and it is also convenient for later debugging and maintenance.
