Claim:
1. A wireless power transfer (WPT)-enabled device, comprising: a communications module configured to communicate with a second WPT-enabled device and to determine a WPT operating parameter associated with WPT between the WPT-enabled device to the second WPT-enabled device; a driver module configured to generate a power signal for charging the second WPT-enabled device according to the WPT operating parameter, the power signal having a first resonant frequency; a tuning module having a first frequency response, the tuning module including a capacitor and a first switch configured to vary the first frequency response by selectively grounding the capacitor; a coupler module having a second frequency response, the coupler module including a coupling element and a second switch configured to vary the second frequency response by shorting a portion of the coupling element; and a controller module configured to adjust the first resonant frequency until the first resonant frequency is substantially similar to a second resonant frequency of the second WPT-enabled device and to control the WPT operating parameter by controlling the first switch or the second switch.
