Abstract :
It is important to use satellite RF power efficiently in restricted satellite resource, especially in case of Ka-band communication systems. For the purpose of efficient use of RF power in satellite systems Ka-band high power multi-port amplifier (MPA) is adopted in WINDS (wideband internetworking engineering test and demonstration satellite) system, this will be launched by the H-IIA launch vehicle in 2008. This paper describes outline of the MPA for WINDS and its test results.
