Abstract
A system includes a plurality of elements that are to operate in a radio frequency (RF) environment. The system further includes a plurality of switching devices to operate in the RF environment, each of the plurality of switching devices to control power to at least one of the plurality of elements, wherein the plurality of switching devices are coupled to a power line that is to provide power from outside the RF environment. A filter is coupled to the power line to filter out RF noise introduced into the power line by the RF environment. The system further includes a converter, coupled to the one or more switching devices, to operate in the RF environment and to provide a non-conductive communication link between the one or more switching devices and a controller outside of the RF environment.
