Techniques are described for managing operations of a wireless-power-transmitting device, capable of operating in multiple radio-frequency (RF) bands. An example integrated circuit includes (i) an interface to couple with a power amplifier, (ii) an encryption block configured to authorize wireless-power-receiving devices, and (iii) a processing subsystem. The processing subsystem is configured to determine, using the encryption block, that multiple wireless-power-receiving devices are authorized to receive wirelessly-delivered power at multiple distinct frequencies. And after determining that the multiple wireless-power-receiving devices are authorized to receive wirelessly-delivered power, the processing subsystem provides multiple input signals, including signals having different respective frequencies, to the power amplifiers via the interface, to be amplified such that, when the amplified signals are sent to antennas, the antennas transmit RF signals to multiple receivers at multiple frequencies. The processing subsystem, interface, and encryption block are on a single integrated circuit.
