1. An integrated circuit for managing operations of a transmitting device, the integrated circuit comprising:

  • a processing subsystem that is configured to control operation of the integrated circuit;

    a waveform generator, operatively coupled to the processing subsystem, configured to generate a plurality of radio frequency (RF) power transmission signals using an input signal;

    a first digital interface that couples the integrated circuit with a plurality of power amplifiers that are external to the integrated circuit;

    a second digital interface, distinct from the first digital interface, that couples the integrated circuit with a wireless communication component that is external to the integrated circuit; and

    a third digital interface directly coupled to an antenna array of the transmitting device,wherein the processing subsystem is further configured to;

    receive, via the second digital interface, an indication that a wireless power receiver is within transmission range of the transmitting device controlled by the integrated circuit, andin response to receiving the indication;

    provide, via the first digital interface, the plurality of RF power transmission signals to at least one of the plurality of power amplifiers.
