Document Type and Number:

WIPO Patent Application WO/2019/146851

Kind Code:

A1

Abstract:

A mobile terminal according to the present invention comprises: a first power amplifier (PA) for amplifying a first signal of a first transceiver and outputting the same; a power combiner for combining a second signal of the first transceiver and a third signal of a second transceiver; a second PA for amplifying a fourth signal combined by the power combiner and outputting the same; and a switch for selecting either a first transmission signal, which is an output signal of the first PA, or a second transmission signal, which is an output signal of the second PA, wherein the first transceiver operates in a first communication system, the second transceiver operates in a second communication system, and the mobile terminal having an improved transmission output power characteristic can be provided by using the first communication system and the second communication system.
