Title: ELECTRONIC DEVICE AND METHOD FOR TRANSMITTING AND RECEIVING SIGNALS
Abstract:
The present invention relates to an electronic device and, more particularly, to an electronic device and a method for transmitting and receiving signals. To this end, the electronic device according to the present invention may comprise: a transceiving unit comprising a first group of power amplifiers (PAs) including at least one PA and a second group of PAs including at least one PA; an antenna unit comprising a first antenna selectively coupled to a PA supporting a first frequency range or a second frequency range of the first group of PAs and the second group of the PAs, and a second antenna selectively coupled to a PA supporting the second frequency range or a third frequency range of the first group of PAs and the second group of the PAs; a power supply unit comprising a first power supply modulator connected to the first group of PAs and a second power supply modulator connected to the second group of PAs; and a communication processor for changing an output voltage at least in part on the basis of transmit power of the PA coupled to at least one of the first power supply modulator and the second power supply modulator, wherein at least one of the first group of PAs and at least one of the second group of PAs are capable of transmitting signals simultaneously.
