According to the application and technical requirements of IoT, a wireless communication architecture based on MAX2830 and FPGA is designed. For RF transceiver circuit, MAX2830 zero IF circuit is adopted to realize 2.4 GHz signal transceiver circuit. For the digital baseband processing unit, the communication algorithm is optimized and transplanted on FPGA, and the open proprietary protocol and the BLE communication protocol are designed and implemented, which are free from authorization. The system performance test verifies the feasibility of the platform. The maximum transmission power is 19.73 dBm, the sensitivity is -88 dBm, and the supported frequency offset range meets the reception requirements. Based on the software radio platform, the communication system and mode can be dynamically reconstructed, which is applicable to a variety of communication scenarios and has important application and research value.
