Abstract
The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). The present disclosure is to amplify transmission signals in a wireless communication system, and a transmitting device may include an antenna array including a plurality of antenna elements, a plurality of amplification chains for amplifying signals transmitted through the plurality of the antenna elements, and a power supply line for supplying powers to the plurality of the amplification chains. Herein, the powers used by power amplifiers included in at least one amplification chain of the plurality of the amplification chains may be divided by filtering or by independent pads and branch-lines.
