Abstract

The invention discloses an LNB (Low-noise block down-converter) module. The LNB module includes an LNB circuit, a satellite positioning signal circuit, an F-type connector and a radio frequency printed circuit board; the radio frequency printed circuit board carries the LNB circuit, the satellite positioning signal circuit and the F-type connector; the LNB circuit and the satellite positioning signal circuit are located at two sides of the F-type connector respectively; and signal received by the LNB circuit and signals received by the satellite positioning signal circuit are combined and outputted together at the F-type connector. In the implementation process of the LNB module, the satellite positioning signal circuit and the LNB circuit are combined, and the satellite positioning signal circuit and the LNB circuit are respectively located at the two sides of the F-type connector, and therefore, interference between the two circuits can be reduced.

Description

technical field [0001] The invention relates to the technical field of satellite television, in particular to an LNB module. Background technique [0002] The Global Positioning System (GPS) uses satellites to provide users with positioning, navigation, mapping, monitoring, and timing services. Satellite positioning has the characteristics of full-time, all-weather, high-precision, continuous real-time navigation, positioning and timing, so it plays a vital role in economic development, social construction and management, scientific research, disaster assessment and prevention and control, and military fields. Its role is related to national defense security and all aspects of people's lives. At present, there are four global positioning satellite systems (GNSS): GPS (Global Positioning System) in the United States, GLONASS (Global Navigation Satellite System) in Russia, Galileo in Europe and COMPASS in China. In terms of civil navigation, the working frequency bands of th...
