Abstract
A dual frequency waveguide switch passes electromagnetic waves in the X-band along one route, and passes electromagnetic waves in the Ku-band along a different route. This switch includes a housing which has first, second, and third openings for the electromagnetic waves to pass through; and a movable member, mounted in the housing, having first and second passageways. The first passageway is shaped to pass electromagnetic waves in both the X-band and the Ku-band, and the second passageway is shaped to pass electromagnetic waves in the Ku-band but reject electromagnetic waves in the X-band. A forcing mechanism forces the moveable member to a position 'A' in the housing where the first passageway interconnects the first opening to the second opening, and to a position 'B' where the second passageway interconnects the first opening to the third opening.
