| Abstract(in English) | Corresponding to the increasing of the data transmission speed from Earth observation satellites, the Japan Aerospace Exploration Agency (JAXA) has been studying the Ultra High-speed Modulator since 2010, which provides more than 2 Giga bit per second (Gbps). Main tasks for achieving the data rate are; (1) the feasibility study of the high-speed Modulation circuits more than 2Gbps, (2) to establish the compensation technology for nonlinear distortion, and (3) the countermeasure against rain attenuation at the Ka-band. This paper describes results of hardware trial productions and evaluations about (1) and (2) for two transmission methods that are64QAM single carrier and 32QAM multicarrier (QAM; Quadrature Amplitude Modulation), and the estimate of the amount of compensation required about (3). |
