Abstract: The development of 5G technology has promoted the application of internet of things technology. With its advantages of low power consumption, long distance and self-organizing network, LoRa has become the preferred solution for IoT wireless communication technology. The demand for LoRa modules has increased significantly, but during the mass production process of LoRa RF modules, the detection of RF performance relies on professional RF detection instruments and automated test procedures, which results in reduced module production efficiency and increased costs. According to the linearity rule of the RSSI parameters of the chip, a radio frequency detection scheme applied to the Sx127x series LoRa module is designed. Compared with the standard instrument test results, the measurement error is within the allowable range. This solution effectively reduces the detection cost and improves the detection efficiency.
