Assignee:

AN INSULATED CIRCULATOR

International Classification:

US Classification:

336/200000

Abstract:

The present invention provides for a grounded circulator that is isolated from the environment. Thus, the circulator of the present invention allows circuit board manufacturers to wash the finished, or partially finished, circuit board after the present invention has been attached to the circuit board without damaging the circulators. The present invention does this by incorporating a novel means for grounding the ferrites of the circulator using a grounding foil wrap so that traditional methods for grounding the ferrites which necessitate that the circulator be unsealed, such as screws and use of the circulator cover, are not used. The present invention also provides for communication by the circulator with other electronic components without compromising the isolation of the interior of the circulator through the use of embedded microstrips.
