Ultra-wideband radial waveguide to coaxial combiner/divider

A system comprising:

• a coaxial input port;
• a coaxial output port;
• a first plurality of N waveguides radially disposed around a first transition, wherein a first end of each of the first plurality of waveguides is operatively connected to the coaxial input port via the first transition;
• a second plurality of N waveguides radially disposed around a second transition, wherein a first end of each of the second plurality of waveguides is operatively connected to the coaxial output port via the second transition;
• and
• a plurality of N amplifiers each having a first port and a second port, wherein the first port of each of the plurality of amplifiers is connected to a second end of one of the first plurality of waveguides and the second port of each of the plurality of amplifiers is connected to a second end of one of the second plurality of waveguides.
