[Background Art] For mobile communication services, an E-UTRAN new radio-dual connectivity (EN-DC) (or dual connectivity) technology for simultaneously connecting two or more communication signals (e.g., LTE network/4G network and 5G network) is applied. In addition, for mobile communication services, a transmission hopping (TX hopping) technology capable of selecting and changing a transmission antenna is applied in order to increase the output efficiency of an electronic device that simultaneously outputs multiple transmission signals. An RF communication structure capable of simultaneously transmitting at least two or more communication signals is applied to an electronic device in order to support the new radio carrier aggregation (NR CA) function, an EN-DC function, and/or a TX hopping function. The above-described information may be provided as related art for the purpose of assisting in understanding the disclosure. No assertion is made as to whether any of the above might be applicable as prior art with regard to the disclosure. [Disclosure of Invention] [Technical Problem] For mobile communication services, there is an increasing demand for supporting new radio frequency (RF) bands and various communication technologies, such as an NR CA function, an EN-DC function, and/or a TX hopping function. To this end, electronic devices have difficulty of adding, to an insufficient mounting space, power amplifiers and power source circuitries for transmission of multiple communication signals. An electronic device including a communication circuitry of the disclosure is to support various communication technologies, such as an NR CA function, an EN-DC function, and/or a TX hopping function. Embodiments of the disclosure provide an electronic device including a radio frequency integrated circuit (RFIC) configured to output multiple radio frequency signals of a first communication network or a second communication network, and a power supply circuitry including a first power source circuitry and a second power source circuitry.
