Abstract: A remote wireless charging transmit end is configured to wirelessly charge a receive end. The transmit end includes a transmit end processor, a fundamental frequency-radio frequency conversion unit, and a transmit end antenna. The transmit end processor is configured to generate a composite signal based on a control signal and a power signal, and send the composite signal to the fundamental frequency-radio frequency conversion unit. The control signal is used to control a working status of the receive end, and the power signal is used to charge the receive end. The fundamental frequency-radio frequency conversion unit is configured to convert the composite signal into a radio frequency signal, and send the radio frequency signal to the transmit end antenna. The transmit end antenna is configured to transmit the radio frequency signal corresponding to the composite signal.
