Abstract: An electronic device includes a battery, a plurality of capacitors, a converter that receives power from the battery and charges each of the plurality of capacitors to different voltages based on the power, a plurality of switches that switch a first path and a second path of each of the plurality of capacitors, and a controller. The controller selects a first switch among the plurality of switches based on a received signal, and controls the first switch such that a path of a capacitor connected to the first switch is switched from the first path to the second path, and the first path is a path which electrically connects each of the plurality of capacitors to the converter, the second path is a path which electrically connects each of the plurality of capacitors and a power amplifier (PA).

Abstract: A circuit board is provided in which a transmission loss is reduced. The circuit board includes a first layer; a transmission line disposed on the first layer; and a second layer stacked with the first layer. The second layer includes a first region, which is constructed of a first material, corresponding to a position of the transmission line, and a second region, which is constructed of a second material having a permittivity that is different from that of the first material, corresponding to the position of the transmission line.
