Abstract: According to one embodiment of the present specification, a user terminal is provided. The user terminal can comprise: a tunable antenna capable of adjusting a band; a diplexer connected to the tunable antenna to synthesize and separate sub-carriers; one or more antenna switches connected to the diplexer to synthesize and separate low-band sub-carriers and middle-band and high-band sub-carriers; and a sub-carrier processing unit connected to the one or more antenna switches to synthesize and separate a plurality of low-band sub-carriers, a plurality of middle-band sub-carriers and a plurality of high-band sub-carriers. A low-noise amplifier can be connected to the sub-carrier processing unit in order to prevent an increase in a reception sensitivity loss and a noise index occurring on a reception path of the diplexer, the one or more antenna switches and the sub-carrier processing unit.
