Abstract

The invention provides a fault detection method and a parameter calibration method of a radio frequency path and a mobile terminal. The fault detection method comprises the steps of: acquiring a first power value of coupling of a first coupler and a second power value of coupling of a second coupler when a radio frequency transceiver outputs power at a target level; comparing the first power value with a first power calibration value in a pre-stored parameter calibration table, which corresponds to the target level, and obtaining a detection result representing whether the radio frequency transceiver has a fault; and comparing the second power value with a second power calibration value in the pre-stored parameter calibration table, which corresponds to the target level, and according to the detection result representing whether the radio frequency transceiver has the fault, obtaining a detection result representing whether a path between a radio frequency amplifier and a radio frequency antenna has a fault. According to the scheme of the invention, by judging whether powers of coupling of two couplers are abnormal, whether the radio frequency transceiver is damaged or the path between the radio frequency amplifier and the radio frequency antenna is damaged can be determined.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a radio frequency path fault detection method, a parameter calibration method and a mobile terminal. Background technique [0002] At present, talking on a mobile phone or using a data service to surf the Internet is an indispensable function for users to use a mobile phone. During the use process, factors such as the quality of the signal and the power consumption of the mobile phone directly affect the experience of consumers. [0003] Among them, the power is mainly coupled by a coupler arranged at the front end of the radio frequency antenna, and the intensity of the power is detected by the radio frequency transceiver, and then the output power of the radio frequency transceiver is controlled according to the power intensity, so as to ensure that the radio frequency signal is transmitted with a Relatively stable power output. However, when the radio frequency fails,...
