Abstract

The embodiment of the invention provides a power calibration method and device for a wireless module. The method comprises the following steps: determining a radiation power attenuation value of a reference module in a shielding box and module signal intensity of a wireless module in the shielding box; determining the actual power of the wireless module according to the radiation power attenuation value and the module signal intensity; and calibrating the transmitting power of the wireless module according to the actual power and the target power. According to the power calibration method and device of the wireless module provided by the embodiment of the invention, the accuracy of crimping test point detection is integrated on the basis of antenna detection, so that the power calibration of the wireless module is accurate.

Description

technical field [0001] The invention relates to the technical field of communication equipment production, in particular to a power calibration method and device for a wireless module. Background technique [0002] The wireless module is very important to ensure the normal operation of the communication equipment, and its power stability is directly related to the performance of the communication equipment. Therefore, the power calibration of the wireless module is an important link in the production process of the wireless module. [0003] For the calibration of the power of the wireless module, the existing technology usually uses a radio frequency switch socket, but the cost of the radio frequency switch socket is relatively high, and it is not suitable for popularization and use. [0004] Another commonly used calibration method is to calibrate the power of the wireless module based on radiation. However, the method of radiometric calibration is less accurate and prone...
