摘要： In embodiments, an electronic device includes a processor, a radio frequency (RF) transceiver, a power amplifier (PA), a dual directional coupler, and an antenna connected to the dual directional coupler. The processor is configured to control the RF transceiver to transmit a first signal of a first frequency band with a first transmission power through the PA, the dual directional coupler, and the antenna. The processor is configured to control the RF transceiver to transmit a second signal of a second frequency band lower than the first frequency band through the dual directional coupler and the antenna while the first signal is transmitted. The processor is configured to control the RF transceiver to identify a forward coupling signal of the second signal and a reverse coupling signal of the second signal among signals obtained from the dual directional coupler. The processor is configured to control the RF transceiver to transmit the first signal based at least in part on the forward coupling signal of the second signal and the reverse coupling signal of the second signal with a second transmission power lower than the first transmission power. In addition to this, various embodiments are possible.
