Modeling and Implementation of a Novel Coaxial Line Multi-Octave High Power Combiners with Low Inter-Modulation Distortion

A novel wide band high power combiner has been developed. The design is optimized for minimal loss, high isolation, and minimal number of ferrite cores. An effective flux canceling circuitry has been implemented to significantly improve its inter-modulation distortion performance. Extensive analysis has been carried out using circuit and EM CAD tools to understand their performance. The combiner has been successfully fabricated, tested, and full performance evaluation will be given in this paper.
