The invention belongs to technical field of satellite communication, be specifically related to satellite communication system airboarne receiver front-end architecture.
Background technology
In the satellite communication system, the airboarne receiver front end system mainly comprises dual-mode antenna and radio-frequency front-end signal processing module (circuit).Because dual-mode antenna need be installed on fuselage surface usually; And the radio-frequency front-end signal processing module need possess anti-electromagnetic interference capability usually; Therefore when design satellite communication system airboarne receiver front-end architecture; Normally dual-mode antenna and radio-frequency front-end signal processing module are installed respectively, and an electromagnetic shielding is used metal cap on the radio-frequency front-end signal processing module outer cover of bearing metal backboard face on bearing metal plate two sides; Simultaneously, consider the environment for use of Airborne Terminal, need between the dual-mode antenna of each path and radio-frequency front-end signal processing circuit, increase lightning arrester, lightning arrester and dual-mode antenna are installed on the same one side of bearing metal plate usually.
Above-mentioned satellite communication system airboarne receiver front-end architecture is as shown in Figure 1; Because dual-mode antenna and radio-frequency front-end signal processing module are installed on bearing metal plate two sides respectively, lightning arrester and dual-mode antenna are installed on one side, and the RF front-end module of bearing metal backboard face needs to increase shielding separately and uses metal cap; And adopt the cable of band SMA connector to connect between each parts; Make that entire front end structural volume and weight are bigger, and connected mode is loaded down with trivial details, reliability and consistency can't be guaranteed.
Summary of the invention
The present invention provides a kind of satellite communication system airboarne receiver front-end architecture, and it is little, in light weight that this front-end architecture has a volume, connection aspect reliable characteristics.
To achieve these goals, technical scheme of the present invention is:
A kind of satellite communication system airboarne receiver front-end architecture, as shown in Figure 2, comprise that bearing metal plate 1, dual-mode antenna 2, radio-frequency front-end signal processing module 3, lightning arrester module 4, coaxial cable 5 and electromagnetic shielding are with metal cover board 6; Said dual-mode antenna 2 is installed on bearing metal plate 1 front; The back side of bearing metal plate 1 has curved cavity; Said radio-frequency front-end signal processing module 3 is integrated in same printed circuit board with lightning arrester module 4 and is installed on the cavity the inside at bearing metal plate 1 back side, and bearing metal plate 1 back side cavity adopts said electromagnetic shielding with metal cover board 6 cappings; The via hole that adopts the coaxial cable 5 of no SMA connector to pass bearing metal plate 1 between dual-mode antenna 2, lightning arrester module 4 and the radio-frequency front-end signal processing module 3 connects.
The invention has the beneficial effects as follows:
Satellite communication system airboarne receiver front-end architecture provided by the invention through digging the chamber and embed the circuit board form in bearing metal backboard portion, has improved integrated level when reducing weight; Lightning circuit module and RF front-end module are integrated on the same printed circuit board simultaneously, have further dwindled volume, have improved system reliability.Directly connect antenna and RF front-end module through coaxial core, abandoned loaded down with trivial details cable connected mode, whole system is firm more, reliable and efficient.Whole receiver front end structure provided by the invention is particularly useful in the mobile system of China's big-dipper satellite communication system.
