The R&D project entitled “Research and Development of Ka-band Wideband Digital Beam Forming for Efficient Frequency Use” has been started since July 2017. The goal of this R&D is the realization of beam location/shape flexibility for Ka-band high throughput satellite (HTS) and the improvement of frequency use efficiency compared with conventional HTS. This DBF payload is developed and planned to be tested in orbit by the engineering test satellite-9 (launch planned in FY 2021). This chapter describes the overview of R&D program and the current outcome of system development.
