Novel High efficiency Broadband Ku band Power Combiner
High power solid-state power amplifiers require a high efficiency power dividing/combining structure to keep the power loss as low as possible. The heat sinking capability of the divider/combiner also limits its maximum output power with continues wave (CW) configuration. In this paper, we introduce a novel 8-way Ku band power divider/combiner system, it demonstrate advantages of low loss, broadband and good heat sinking capability simultaneously. As its sub-components, low loss probes for waveguide-tomicrostrip transition and low loss broadband l-to-2 power combiners are designed and fabricated. The measured back-to-back insertion loss of the whole 8way power combiner is lower than 0.5dB in the whole Ku band, and the corresponding combining efficiency is as high as 94.5％. The simulated thermal resistance of the system is as low as 0.21°C/W, indicating the proposed power combiner is able to produce SOW of CW output power with commercial available Monolithic Microwave Integrated Circuits (MMICs).
