Some embodiments relate to a multi-mode wireless power transmitter. The transmitter includes an inverter configured to produce at its output a first signal having a first frequency or a second signal having a second frequency. The transmitter also includes a first transmit coil coupled to the output of the inverter and configured to wirelessly transmit power at the first frequency. The transmitter also includes a second transmit coil coupled to the output of the inverter and configured to wirelessly transmit power at the second frequency. The transmitter further includes at least one matching network coupled to the first transmit coil, the second transmit coil, and the output of the inverter. The at least one matching network is configured to provide power to the first transmit coil in response to the first signal and inhibit providing power to the second transmit coil in response to the first signal.
