Broadband Radial Waveguide Power Combiner With Improved Isolation Among Adjacent Output Ports

Abstract: Abstract-An eight-way waveguide-based power combiner/divider is presented and investigated in the frequency range 7.5-10.5 GHz. A simple approach is proposed for design purposes. The measured combiner shows a good agreement between the simulated and measured results. Insertion loss is about −0.3 dB, return loss is less than −15 dB and isolation between adjacent output ports is better than −11 dB at 8.5 GHz and reaches about −14 dB at 9.5 GHz.

“…Dimensions and weight are two of the most important features in satellite applications which is why this architecture was chosen. The combining efficiency is not the maximum achievable with current systems, such as radial combiners [19][20][21][22][23][24], but the power-to-weight ratio and power density are definitely the best in literature up to this point, as shown in [8]. To conclude, multiphysics simulations certify the suitability of the system for space environments.…”
