Abstract: A mobile terminal includes a first power amplifier configured to amplify and output a first signal of a 5G communication system; a first antenna connected to the first power amplifier and configured to transmit the first signal amplified and output from the first power amplifier as a first transmission signal; a second power amplifier configured to amplify and output a second signal of the 5G communication system; a second antenna connected to the second power amplifier and configured to transmit the second signal amplified and output from the second power amplifier as a second transmission signal; and a power controller connected to the first power amplifier and the second power amplifier and including a common voltage booster configured to provide a supply voltage to both of the first power amplifier and the second power amplifier at a same timing.
