Description

technical field [0001] The invention relates to a single-board radio frequency system for microwave and millimeter waves, in particular to an X-band substrate integrated waveguide single-board radio frequency system that can be used for microwave and millimeter waves. Background technique [0002] The development of communication technology requires easy integration, miniaturization, light weight and high reliability of various components. In a traditional high-performance microwave communication system, each radio module, antenna, duplexer, and intermediate frequency circuit are structurally separated from each other. The reason is that in order to improve performance, various components are realized by different technologies, such as reflector antennas or dipole antennas for antennas, traditional metal waveguide cavity duplexers for duplexers, and metal waveguide filters or ceramic filters for radio frequency filters. Devices, etc., intermediate frequency circuits and ind...
