ABSTRACT:
A multiposition microwave switch with a cavity comprising a center and a plurality of spaced radial portions which are narrowed at one end contiguous with the center. For a given number of radial portions, or switch positions, the diameter of the center is thereby made smaller than that which could be achieved by the prior art, and thereby extending the frequency range of the prior art.
