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

The transceiver is composed of a transmission power controller, a transmission frequency converter, a transmission synthesizer, a crystal oscillator, a radio frequency filter bank, a receiving frequency converter, a receiving synthesizer, an intermediate-frequency filter, a power supply, a monitor and the like. According to the X-frequency-band ground-to-air transmission broadband transceiver, the modular design is adopted for all circuits, the transceiver has the advantages that the integration level is high, the size is small, the working frequency band is wide, the functions are complete, the types of devices are easy to select, the debugging difficulty is low, use is simple, and the universality is good, and the transceiver is particularly applicable to an X-frequency-band broadband digital microwave communication system.

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...
