Claim:
1. A receiver for receiving power wirelessly, comprising: an antenna configured to receive power wirelessly from a transmitter; a wireless power circuit configured to provide the power to a load and configured to operate according to a first frequency; a communication circuit configured to operate according to a second frequency; and a circuit coupled between the antenna and the wireless power circuit and coupled between the antenna and the communication circuit, the circuit comprising a first resonant network and a second resonant network, the circuit comprising a first path between the antenna and the wireless power circuit via the first resonant network and a second path between the antenna and the communication circuit via the second resonant network, the first resonant network comprising a first set of switches and the second resonant network comprising a second set of switches, the first path having a higher impedance than the second path at the second frequency when the first set of switches and the second set of switches are activated and having a lower impedance than the second path at the first frequency when the first set of switches and the second set of switches are deactivated.
