Application circuit composed of CSJ-R05B and microcontroller

CSJ-R05B is an industrial-grade superheterodyne miniature receiving component. It is based on the CSJ-R05A component and adds a local oscillator for surface acoustic wave oscillator frequency stabilization and a sleep (power saving) control circuit. It has good adaptability to changes in temperature, power supply voltage and usage environment, and can meet the usage requirements in harsh environments. The application circuit of CSJ-R05B and microcontroller is shown in the figure below.
