Abstract

The invention provides a detection method of a radio frequency path and a mobile terminal. The method comprises the following steps: detecting power index of the radio frequency path during transmitting data; determining whether the power index meets a preset condition that the path is abnormal; determining that the radio frequency path is abnormal if the power index meets the preset condition that the path is abnormal; and outputting a prompt message associated with the the radio frequency path abnormality. Through the method, the prompt message that the radio frequency path is abnormal can be output immediately when the radio frequency path is abnormal so as to provide feedback that the radio frequency path is abnormal to the user in time.

Description

technical field [0001] The invention relates to the communication field, in particular to a radio frequency path detection method and a mobile terminal. Background technique [0002] With the development of science and technology, mobile terminals (such as mobile phones, notebooks, and tablet computers) with radio frequency access functions have been widely used in various fields of our lives. The radio frequency path in the mobile terminal is often used to transmit and receive communication signals. The current radio frequency path includes a transceiver, a power amplifier, a duplexer, an impedance matching network, a coupler, and a feedback path. During the transmission process, the transceiver generates The low-power transmission signal is amplified by the power amplifier, and then transmitted to the coupler through the duplexer. The coupler couples the transmission signal to obtain two output signals, one of which is modulated and then transmitted through the antenna. T...
