A multiple waveguide junction such as a magic T is described capable of coupling large average and peak powers with a low standing wave ratio over a wide bandwith. The magic T structure employs waveguide arms which meet at a common junction region and has a plane of symmetry that bisects both the E and H input waveguide arms. The latter arms each have necked down segments so as to improve the bandwidth of the structure. Impedance matching elements are employed in the junction region. One element has a ridge-like shape selected to provide an impedance match to the H input waveguide arm. Other matching elements are employed to provide a low SWR over a bandwidth that approaches a 3:1 ratio.
