Abstract
An RRH includes a power supply device, an AISG interface, a PA, and a control unit. The PA is operated by a power source with a first voltage or a second voltage that is lower than the first voltage and amplifies a transmission signal. The AISG interface is connected to an antenna control device operated by the power source with the second voltage. The power supply device supplies the power source to the PA and the power source to the antenna control device to the AISG interface. When the antenna control device is operated, the control unit controls such that the power supply device generates the power source with the second voltage, supplies the generated power source to the PA and the antenna control device, and increase power of the transmission signal output from the PA that is operated by the power source with the second voltage.
