The invention provides a highly integrated Ku-band satellite television tuner structure, which comprises an antenna, a low-noise amplifier and a low-noise down converter, wherein the antenna is used for receiving satellite signals; the low-noise amplifier is connected with the antenna and the low-noise down converter and integrated with a vertical polarization low-noise amplifying circuit and a horizontal polarization low-noise amplifying circuit at the same time, and is used for performing vertical polarization low-noise amplification processing or horizontal polarization low-noise amplification processing on the satellite signals according to a gating signal of the low-noise down converter; and the low-noise down converter is used for performing down conversion processing on the satellite signals processed by the low-noise amplifier. The highly integrated Ku-band satellite television tuner structure not only reduces the area of a Ku-band satellite television tuner chip and a peripheral circuit, but also enables the Ku-band satellite television tuner structure to achieve the effects of low cost, high gain and low noise.
Description
technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a highly integrated Ku-band satellite TV tuner structure. Background technique [0002] With the rapid development of information technology and the rapid development of integrated circuits, Ku-band satellite TV tuner technology, which is the most important and core of integrated circuits, has also been greatly developed. With the rapid development of satellite technology in recent years, Ku-band satellite TV can be seen everywhere and plays an increasingly important role in people's daily entertainment life. People are increasingly inseparable from the variety of satellite TV. [0003] The Ku-band satellite TV tuner is located at the front end of the satellite TV receiver. Its main function is to amplify the weak signal and modulate the RF signal to the intermediate frequency to extract the useful signal. It plays a vital role in reducing noise interference and impro...
