Abstract
A conical TEM power divider/combiner (10) comprises an input port (12), a first circular waveguide (14), a coaxial device (16), a plurality of amplifiers (18), a plurality of cooling fins (20), a second circular waveguide (22), an output port (24), a conical dividing waveguide (42, 32), a first parallel plate waveguide (40, 50), a second parallel plate waveguide (40, 52) and a conical combining waveguide (34, 44). The input port (12) is coupled to the first circular waveguide (14). The first circular waveguide (14) is in turn coupled to the coaxial device (16). The coaxial device (16) divides the signal using the conical dividing waveguide (42, 32), a first parallel plate waveguide (40, 50), and a first plurality of striplines (54). The striplines (54) couple the first parallel plate waveguide (40, 50) to the inputs of the plurality of amplifiers (18). The amplifiers (18) each amplify a respective divided signal and output the result to the second the second parallel plate waveguide (40, 52). The signals are recombined by the second parallel plate waveguide (40, 52) and the conical combining waveguide (34, 44). The amplified signal is then transformed to a rectangular mode signal by the second circular waveguide (22) and port (24).
