| Abstract: | This paper presents the method of extending product application area by adopting low noise amplifier （LNA） and power amplifier （PA） in front of the RF, which is based on the TDA5255 cored wireless data send and receive module. The system is modulated by FSK, and is controlled by I2C. It has the frequency band of 430MHz--432MHz, and the transmission distance about 1500 meters. Experiments show that this system module has a factual measure distance of 1310 meters, which can satisfy the requirement of DRKE system. |
