Description

technical field [0001] The invention relates to an X-band ground-to-air transmission broadband transceiver in the field of broadband digital microwave communication, and is especially suitable for use as high-frequency communication equipment in a ground-to-air transmission digital microwave communication system. Background technique [0002] Broadband data link is a type of data link system that mainly transmits tactical intelligence information such as images, videos, and radars, and has line-of-sight and beyond-line-of-sight capabilities and networking functions. It is called a broadband data link. The broadband data link has a communication bandwidth unmatched by other data links, and can well solve the problem of high-speed transmission of large-capacity reconnaissance intelligence such as images and videos in network-centric warfare. Therefore, it is of great significance to develop miniaturized, generalized, and modularized transceivers that support ultra-high commun...

Problems solved by technology

[0003] At present, in the research and development of domestic transceivers, the field of civilian products is subject to the constraints of the National Radio Commission on the allocation of signal bandwidth and radio resources. High-order modulation technology can only be developed within a narrow channel bandwidth, which will affect the overall power consumption and power amplifier efficiency. , radio frequency linearization and other indicators put forward extremely high requirements, and it is difficult to adapt to the new requirements of miniaturization, high-speed, and long-distance transmission of air platform equipment; the traditional transceiver bandwidth in the field of military products is only tens of MHz, and it is difficult to adapt to the transmission of broadband signals. With the development of high-speed AD / DA and large-scale FPGA, high-speed broadband parallel processing algorithms have also been developed rapidly, and there is an urgent need for matching broadband transceivers for ground-to-air transmission
