摘要: This letter presents the development of a ${\rm X/K}u$ -band (8–18 GHz) radial waveguide combiner for solid state power amplifiers. The proposed utilizes novel to coaxial transition which allows ultra-wideband performance. Simulation results show 1 dB insertion loss bandwidth 9.5 GHz this combiner. Finally, both computer numerical control (CNC) machining and direct metal laser sintering (DMLS) stereo-lithographical processes are investigated as potential fabrication methods.
