Evolution and Trends of High-Q Filters for Satellites
Abstract
This presentation will review the evolution of microwave passive filter devices for China's communication satellites with focus on the exploration and development of microwave passive devices in ultra-high Q, high frequency, integration, miniaturization and high power driven by the demands of advanced communication satellite payload technologies. Furthermore, in light of recent advances in Low Earth Orbit (LEO) internet satellites and high-throughput satellites in recent years, the presentation will also look forward to the future trend of microwave passive devices for satellites, including all dielectric filters, integration of filter antennas, and on-board application prospects of chip filters.
Biography of the speaker
Dr. Li Shengxian has been a program manager in China Academy of Space Technology (Xi'an) for many years in charge of space communication payloads and instruments, including antennas, receivers, power amplifiers, filters/multiplexers and onboard digital processors, etc.
Dr. Li graduated from Xi'an Jiaotong University and received the Ph. Degree in electromagnetic field theory and microwave technology. He joined China Academy of Space Technology (Xi'an) as a member of technical staff in 1999. His early research was focused on CAD, CAT (computer-aided tuning) of RF/microwave passive devices, and EM numerical simulation technologies. Now he focuses on the research of system aspects of space communication payloads.
Dr. Li has not only the extensive knowledge and expertise in the technical aspects in space microwave payloads but also rich management experience in promoting new technologies to advanced communication satellites.
