Abstract
An electric device for receiving a radio frequency (RF) signal is provided. The electric device includes an antenna, a first power amplifier, a battery, a second filter and a second power amplifier. The antenna is used for receiving and outputting a RF signal. The first power amplifier is used for receiving the RF signal, amplifying the RF signal and outputting the RF enhanced by the first power amplifier and a feedback signal. The battery is used for providing a working voltage to the first power amplifier, and receiving and outputting the feedback signal. The second filter is used for receiving the working voltage provided by the battery and the feedback signal, filtering the feedback signal and outputting the working voltage. The second power amplifier is used for receiving the working voltage.
