| Abstract: | In order to meet the requirement for the feeding system of high power microwave(HPM) radiation antenna and overcome the shortage of current multi-port high power divider,a novel 16-way high power divider was developed.The novel high power divider is composed of coaxial waveguide-4-way rectangular waveguide ,H-T branch and rectangular coaxial waveguide,and the 16 outputs of the divider are characterized of equivalent amplitudes and phases.The 16-way high power divider was designed and tested with a center frequency of 2.85 GHz.The experiment results show that at the center frequency,the insertion loss is about 0.4 dB,the voltage standing wave radio(VSWR) is about 1.3,and the output power and phase imbalances are about 0.7 dB and 5° respectively.In the range of 2.78 to 2.92 GHz(5% bandwidth of the center frequency),the insertion loss and the VSWR are below 0.6 dB and 1.5 respectively.The input coaxial waveguide is the bottleneck of the power capacity of the divider so that this characteristic permits the divider to realize the power dividing of HPM source. |
