Abstract
A wireless communication system includes an antenna, a receiving module, a power source, and a power control hub. The power control hub includes an amplifier having a first end coupled to the receiving module and a second end coupled to the power source. The amplifier generates a first output signal based on a control signal of the receiving module. The power control hub includes a rectifier having a first end coupled to the output end of the amplifier and a second end coupled to the power source. The rectifier generates a second output signal based on the first output signal. The power control hub also includes a switch. A first and a second end of the switch are electrically connected or disconnected based on the second output signal received at a control end of the switch.
