Abstract
A radio frequency (RF) power source for use with a wireless power transmitter is provided. A direct current (DC) voltage supply of the RF power source supplies a substantially constant DC voltage to RF power source circuitry of the RF power source. A first node of the RF power source circuitry is electrically coupled to a first terminal of the DC voltage supply. The RF power source circuitry has first and second terminals that are electrically coupled to first and second terminals, respectively, of a resonant magnetic loop antenna of the wireless power transmitter circuit to provide an RF current having a constant amplitude to the resonant magnetic loop antenna.
