Classification: CPC H | IPC H

Claim 0:
1. A wireless power transmission system comprising:
a transmitter antenna configured to couple with at least one other antenna and transmit alternating current (AC) wireless signals to the at least one other antenna, the AC wireless signals including wireless power signals and amplitude shift keying (ASK) wireless data signals;
an integrated circuit including:
a transmitter controller that is configured to (i) provide a driving signal for driving the transmitter antenna based on an operating frequency for the wireless power transmission system and (ii) perform one or more of encoding the ASK wireless data signals, decoding the ASK wireless data signals, receiving the ASK wireless data signals, or transmitting the ASK wireless data signals; and

an amplifier, the amplifier including:
at least one transistor that is configured to receive the driving signal at a gate of the at least one transistor and invert a direct current (DC) input power signal to generate the AC wireless signals at the operating frequency, and
a damping circuit that is configured to dampen the AC wireless signals during transmission of the ASK wireless data signals, wherein the damping circuit includes at least a damping transistor that is configured to receive, from the transmitter controller, a damping signal for switching the damping transistor to control damping during transmission of the ASK wireless data signals.
