| 摘要 |
The present invention relates to a mobile terminal and an output compensation method for power amplifier thereof for compensating output performance degeneration generated when amplifying signals related to a plurality of communication methods by using an individual power amplifier and comprises: a step of measuring output characteristics of a power amplifier (PA) per battery voltage; a stage of storing a plurality of measured PA output characteristics; a step of variably selecting the different PA output characteristics stored according to voltage variations of the battery; and a step of generating a correction value corresponding to the selected PA output characteristics and pre-distorting input of the power amplifier unit. |
