Abstract: A method may include switching to a first mode based on identifying that a condition for activating the first mode for transmitting and receiving a signal in a first frequency band is satisfied, converting, using an RFIC in the first mode, data to be transmitted to an external electronic device into a first signal in a second frequency band, mixing the first signal with a second signal in a third frequency band using a first mixer in an RF circuit connected to the RFIC to generate a third signal in the first frequency band, and amplifying, using a PA in the RF circuit, the third signal based on a set gain to generate a fourth signal, and transmitting the fourth signal to the external electronic device using at least one antenna.

Abstract: Disclosed is an electronic device including: first communication circuitry including a first amplifier, second communication circuitry including a second amplifier, a transceiver, a processor, and a power supply. The processor may be configured to: provide, to the first communication circuitry, a first voltage for transmitting a first signal using the power supply in a first time interval, and provide, to the second communication circuitry, a second voltage for transmitting a second signal using the power supply in a second time interval that does not overlap the first time interval.

Abstract: An electronic device is provided. The electronic device includes an antenna, a transmission path electrically connected to the antenna and including at least one amplifier, a transceiver connected to the transmission path and converting a signal, a feedback path connected between the transmission path and the transceiver, at least one processor connected to the transceiver and communicating with at least one external electronic device by using the transceiver, and a memory connected to the at least one processor. The processor may obtain first information about a first phase and a first magnitude, which are associated with the first frequency, and second information about a second phase and a second magnitude, which are associated with a multiplied frequency of the first frequency, from the transmission signal and the reflection signal using the transceiver, and may determine a state of the electronic device based on the first information and the second information.
