| Abstract(in English) | A high-speed downlink communication system is required to meet various applications for nano/small satellites. Therefore, it is essential to implement a transmitter with small weight and power in such satellites. We have developed high speed communication system over 300 Mbps for small satellite. In order to reduce DC power consumption of transmitter, we have developed GaN-HEMT power amplifier for X band downlink. The Hodoyoshi-4 satellite equipped with the developed communication system was launched in 2014 and we demonstrated 348 Mbps downlink from 50-kg class satellite. This paper describes the summary of the developed system, the experiment of high speed downlink, and future works. |
