Abstract

The invention provides a method and a mobile terminal for improving emission spurs. The mobile terminal includes a transmitter, a power amplifier, a first variable notch module and a second variable notch module, the first variable notch module is respectively connected to the output end of the transmitter and the input end of the power amplifier, and the second variable notch module The variable notch module is connected to the output end of the power amplifier. The method includes: adjusting the working state of the transmitter and / or the power amplifier when the mobile terminal has transmission spurs; if the transmission spurs do not meet the preset conditions, adjusting Notch frequencies of the first variable notch module and / or the second variable notch module. The present invention automatically improves the transmission spurs of the mobile terminal when there are transmission spurs when the mobile terminal leaves the factory, so as to make the transmission spurs of the mobile terminal meet the preset conditions as much as possible, without the need for professional engineers to check the mobile terminals that do not meet the requirements one by one Analysis and debugging can greatly reduce the time and cost of debugging mobile terminal emission spurious problems.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method for improving spurious transmission and a mobile terminal. Background technique [0002] The transmission spurious of the mobile terminal sometimes affects the communication performance of the mobile terminal itself. For example, when the transmission spurious of the mobile terminal falls into the receiving frequency band of the mobile terminal, it will affect the communication performance of the mobile terminal itself. It will affect other wireless devices, or even cause interference to other wireless devices and make it impossible to communicate normally. Therefore, the National Radio Commission controls the spectrum resources, and the emission spuriousness of the mobile terminal must meet the emission spurious requirements of the National Radio Commission, so that the emission spuriousness of the mobile terminal will not affect other systems or equipment, and...
