| Abstract(in English) | In satellite transponders, a mixer with low spurious characteristics is required for reducing the interference between communication channels. Also a mixer with a gain flatness is required for obtaining a high transmission quality. To achieve these requirements, improvements of a division accuracy, a flatness of insertion loss and a port-to-port isolation are required for a 180 degree hybrid circuit used in a balanced mixer. In this paper, a novel slotline type 180 degree hybrid power divider is proposed for a balanced mixer utilization. Also characteristics of the proposed divider is described. In this divider, a new isolation circuit is connected with series T junction consisting of a slotline and a microstrip line. Effectiveness of the proposed divider is clarified by analytical and experimental approaches. Furthermore a developed Ka-band balanced drain mixer for a satellite transponder is described. |
