TRANSMITTER AND METHOD FOR WIRELESS CHARGING, AND TERMINAL

Provided are a transmitter and method for wireless charging, and a terminal. The transmitter for wireless charging includes: an input circuit, configured to receive a first alternating-current electric signal of a first frequency; a first conversion circuit, configured to convert the first alternating-current electric signal into a second alternating-current electric signal of a second frequency; and at least one first radio frequency antenna, connected with the first conversion circuit and configured to convert the second alternating-current electric signal into a radio frequency signal for wireless charging and transmit the radio frequency signal. Therefore, long-distance wireless charging may be implemented based on a characteristic that the radio frequency transmitted by the transmitter for wireless charging may be transmitted at a long distance and may penetrate a nonmetallic object, and a user experience is improved.
