Abstract
A wireless power source including a microwave receiver, a matching network, and a transducer. The microwave receiver receives a microwave signal having a carrier frequency. The matching network receives a signal having the carrier frequency and a switched frequency and removes the carrier frequency such that the matching network outputs a switched signal at the switched frequency. The transducer is configured to receive the switched signal and output a DC voltage.
