HIGH POWER RF FIELD EFFECT TRANSISTOR SWITCHING USING DC BIASES

摘要

Systems, methods, and apparatus are provided for tuning in wireless power transfer circuits. One aspect of the disclosure provides an apparatus for tuning. The apparatus includes a field effect transistor having a gate, source, and drain, where the field effect transistor is configured to electrically engage a tuning element to an AC power path. In some embodiments, one of the source or drain contacts is at an alternating current voltage.
