Data Transmission Transmitter
basic information
Data Transmission Modulators include five kinds of products, which main function is to complete the coding and modulation of satellite. The working frequency of these products covers L/S/X/Ka ,and their transmission speed meets the requirement of 5Mbps~3Gbps. These products can be used for LEO, MEO and GEO satellites and other spacecrafts according to different requirement.
