SiBCN (silicon boron carbon nitrogen) wireless passive microwave resonant cavity temperature sensor is a new type of sensor under the development trend of radio frequency microwave technology. Based on the working principle of the sensor, the software design of SiBCN temperature sensor wireless sweep transceiver system based on FPGA is carried out on the basis of the existing wireless sweep signal transceiver system hardware. Let the signal source send the 11.0GHz ~ 11.6GHz range sweep signal to the sensor. The feedback signal of the sensor is filtered and the resonant frequency is obtained. The detection of temperature is based on the correspondence between the resonant frequency and the temperature.Through the analysis of the measured results, the system software design meets the requirements, and the temperature and frequency change rate is about 421.2KHz / °C.
