1. An apparatus comprising:
an inner conductor comprising (a) a cylindrical portion, (b) a tapered end and (c) a plurality of blades, wherein (i) said plurality of blades (A) are arranged evenly spaced around said cylindrical portion and (B) each extend along a length of said cylindrical portion with an edge having a predetermined shape, (ii) said edge of each of said plurality of blades has a probe at a first end and a second end of said edge of each of said plurality of blades gradually meets said cylindrical portion a distance from said tapered end and (iii) said tapered end has an input/output (I/O) transition; and
an outer conductor comprising (a) a cavity, (b) a first coaxial connector and (c) a plurality of second coaxial connectors, wherein (i) said inner conductor is within said cavity, (ii) said first coaxial connector is connected to said I/O transition of said tapered end, (iii) each of said plurality of second coaxial connectors is connected to said probe of one of said plurality of blades and (iv) said predetermined shape of said edge of each of said plurality of blades is configured to provide a low-loss transition for a microwave signal propagating between (a) each of said plurality of second coaxial connectors and (b) said first coaxial connector.
