Problems solved by technology

At present, some receivers on the market have narrow operating frequency bands, most of which are 950-1450M, or those with high frequencies are also segmented, and have no tracking ability. They only detect signals and have poor ability to extract weak signals. Relatively low, it is easy to cause misjudgment of the received signal

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to an ultra-wideband integrated tracking receiver. Background technique [0002] In recent years, satellite emergency communications have developed rapidly. Many low-orbit and geostationary-orbit satellites have been launched. The satellite communication frequency band has also been extended to the KA band. The frequency band is wider and the speed is faster. The satellite communication ground station has also developed. , the performance of component components is also improving, and it is developing towards miniaturization, intelligence, and broadband compatibility. The tracking receiver is one of the core key components of the satellite ground station system. Transmit power to achieve stable, reliable and economical communication; or in order to obtain satellite orbit data, monitor or correct the position of the satellite, the ground antenna must be accurately poi...
