Abstract
A data transmission system is designed for the SDGSAT-1 small satellite to meet the high-speed data processing and transmission requirements. The data transmission system consists of two principal components: the transmitter and the steerable transmission antenna. To satisfy the satellite link budget requirement, the 37.5 dBm X-band transmitter has been developed for an 810 Mbps data rate with 8PSK modulation. The dual circularly polarized antenna with a pointing mechanism has a gain of over 20 dBi, and the pointing accuracy error is less than 0.110°. The data transmission system’s EIRP exceeds 28 dBW. On-orbit operations have demonstrated that the data transmission system exhibits excellent performance and high reliability.
期刊介绍：
International Journal of RF and Microwave Computer-Aided Engineering provides a common forum for the dissemination of research and development results in the areas of computer-aided design and engineering of RF, microwave, and millimeter-wave components, circuits, subsystems, and antennas. The journal is intended to be a single source of valuable information for all engineers and technicians, RF/microwave/mm-wave CAD tool vendors, researchers in industry, government and academia, professors and students, and systems engineers involved in RF/microwave/mm-wave technology.
Multidisciplinary in scope, the journal publishes peer-reviewed articles and short papers on topics that include, but are not limited to. . .
-Computer-Aided Modeling
-Computer-Aided Analysis
-Computer-Aided Optimization
-Software and Manufacturing Techniques
-Computer-Aided Measurements
-Measurements Interfaced with CAD Systems
In addition, the scope of the journal includes features such as software reviews, RF/microwave/mm-wave CAD related news, including brief reviews of CAD papers published elsewhere and a "Letters to the Editor" section.
