Abstract
One aspect of the present invention includes an RF including a first mixer receiving an RF signal. A second mixer also receivers the RF signal. A resonant circuit couples to a common input of the first mixer and the second mixer. A second polyphase reactive circuit coupled to an output of the second mixer. In one embodiment, a direct current circuit coupled to the output of the first mixer, injecting direct current into the system. The resonant circuit is set at a resonance frequency such that a voltage across the second polyphase reactive circuit is a predetermined voltage.
