Abstract:
1. A ferrite element for a switchable circulator, the ferrite element comprising: a first segment extending in a first direction from a center portion of the ferrite element; a second segment extending in a second direction from the center portion of the ferrite element; and a third segment extending in a third direction from the center portion of the ferrite element; wherein each of the first segment, the second segment, and the third segment include a first channel located at a first distance from a center point of the ferrite element, the first distance defining a first resonant section of the ferrite element; wherein each of the first segment, the second segment, and the third segment include a second channel located at a second distance from the center point, the second distance defining a second resonant section of the ferrite element; wherein the first channel is sized to enable a first wire capable of carrying a current pulse to be passed through the first channel; wherein the second channel is sized to enable a second wire capable of carrying a current pulse to be passed through the second channel; wherein, when a current pulse is applied to the first wire, performance of the switchable circulator operating in a first frequency band meets desired performance levels better than when a current pulse is applied to the second wire; and wherein, when a current pulse is applied to the second wire, performance of the switchable circulator operating in a second frequency band meets desired performance levels better than when a current pulse is applied to the first wire.
