Circuit for Managing Wireless Power Transmitting Devices

An integrated circuit for managing operations of a radio frequency (RF) power transmitter, the integrated circuit comprising:

• an RF subsection for DC to RF power conversion, the RF subsection configured to convert an input current provided to the integrated circuit into one or more RF power transmission signals;
• an encryption module configured to ensure that only authorized wireless power receivers are able to receive wirelessly delivered power from the RF power transmitter;
• a first interface configured to couple the integrated circuit with at least one power amplifier that is external to the integrated circuit;
• a second interface, distinct from the first interface, configured to couple the integrated circuit with a wireless communication component that is external to the integrated circuit;
• and
• wherein the integrated circuit is configured to:
• receive, via the second interface, an indication that a wireless power receiver is within transmission range of the RF power transmitter controlled by the integrated circuit, and
• in response to receiving the indication, and after determining using the encryption module that the wireless power receiver is authorized to receive wirelessly delivered power from the RF power transmitter, provide, via the first interface, the one or more RF power transmission signals to the at least one power amplifier.
