Abstract
Description
Technical Field
[0001] This application relates to the field of amplifier technology, especially low-noise down-amplifiers, specifically an eight-output novel KU-band high-frequency head PC board circuit structure. Background Technology
[0002] A low-noise block downconverter (LNB) is a type of low-noise downconverter amplifier, consisting of a mixer and a local oscillator. LNBs are generally divided into C-band LNBs (3.4GHz-4.2GHz) and Ku-band LNBs (10.7GHz-12.75GHz).
[0003] In actual signal transmission, the satellite's signal is quite weak before it reaches the antenna, and the higher the frequency of coaxial cable transmission, the greater the signal loss. Therefore, an LNB is needed to amplify the signal, but the signal-to-noise ratio cannot be degraded too much during amplification.
[0004] When performing low-noise down-amplification, the LNB's workflow is as follows: first, the high-frequency satellite signal is amplified, then the local oscillator circuit is used to convert the high-frequency satellite signal to an intermediate frequency of 950MHz-2150MHz (the intermediate frequency range depends on the type of LNB) and amplify it again to facilitate the transmission of the coaxial cable and the demodulation and operation of the satellite receiver.
[0005] Currently, common eight-output LNBs suffer from problems such as numerous components, large size, heavy weight, many assembly processes, and large PCB area, making it difficult to meet the demands of modern electronic devices for miniaturization, integration, and high efficiency.

[0023] This embodiment discloses a novel eight-output KU-band high-frequency head PC board circuit structure, including:
[0024] Polarization probe hole H and polarization probe hole V are used to receive satellite signals;
[0025] The LNA low-noise amplifier has polarization probe holes H and V connected to its input terminal. The LNA low-noise amplifier input terminal is used to receive satellite signals received by polarization probe holes H and V and amplify them.
[0026] The input terminal of the common divider is connected to the output terminal of the LNA low-noise amplifier.
[0027] The input terminal of the MMIC integrated circuit chip is connected to the output terminal of the common factor.
[0028] The F-hole is connected to the output terminal of the MMIC integrated circuit chip. The F-hole is used to output the signal processed by the MMIC integrated circuit chip.
[0029] The PCB body has polarization probe holes H, polarization probe holes V, LNA low noise amplifier, divider, MMIC integrated circuit chip and F-head hole.
[0030] Based on the above, this embodiment utilizes polarization probe holes H and V to receive satellite signals and transmit them to the input of the LNA (Low Noise Amplifier). The LNA amplifies the signal, then a common divider splits the amplified signal into two paths before inputting them into the MMIC (Multi-Integrated Circuit) chip. Within the chip, mixing, intermediate frequency amplification, and signal distribution are performed. Finally, the processed signal is output through the F-port, achieving efficient reception, amplification, distribution, and output of satellite signals in an eight-output novel KU-band LNB PCB circuit structure. Throughout the process, all components work closely together. Compared to traditional eight-output LNBs, this effectively reduces the number of components, shrinks the device size and weight, simplifies the assembly process, and reduces PCB footprint. It meets the demands of modern electronic devices for miniaturization, integration, and efficiency, improves the performance and efficiency of satellite signal processing, and enhances adaptability and competitiveness in practical applications.
[0031] Specifically, polarization probe hole H is used to receive horizontally polarized satellite signals, and polarization probe hole V is used to receive vertically polarized satellite signals.
[0032] By utilizing the design described above—polarization probe hole H specifically for receiving horizontally polarized satellite signals and polarization probe hole V specifically for receiving vertically polarized satellite signals—this embodiment achieves precise reception of satellite signals with different polarizations. This approach ensures that satellite signals are effectively distinguished and efficiently utilized from the initial stage of entering the circuit system, avoiding interference and confusion between signals of different polarizations. It provides a high-quality input signal source for the subsequent targeted amplification processing of the LNA low-noise amplifier, thereby improving the accuracy and stability of the entire circuit structure in processing satellite signals, optimizing the signal processing flow, and enhancing the performance and reliability of the new eight-output KU-band LNB.
[0033] Specifically, the divider is used to split the signal amplified by the LNA low-noise amplifier into two signals.
[0034] Based on the above, this embodiment utilizes the common divider to distribute the signal amplified by the LNA low-noise amplifier into two signals, achieving parallel signal processing. This distribution method provides multiple signal input paths for subsequent operations such as mixing, intermediate frequency amplification, and signal distribution within the MMIC integrated circuit chip, effectively improving the efficiency and flexibility of signal processing. This allows signals to flow and be processed more orderly and efficiently among components in the eight-output novel KU-band LNB PC board circuit structure, optimizing the overall circuit's signal transmission and processing architecture, enhancing the circuit system's ability to process and adapt to satellite signals, and ensuring the quality and stability of the final eight-output signals.
[0035] In summary, the eight-output novel KU-band LNB PC board circuit structure of this embodiment utilizes polarization probe holes H and V to receive satellite signals and transmit them to the input of the LNA low-noise amplifier. The LNA amplifies the signal, and then the amplified signal is split into two paths by a common divider before being input to the MMIC integrated circuit chip. The chip performs mixing, intermediate frequency amplification, and signal distribution operations, and finally outputs the processed signal through the F-head hole. This achieves efficient reception, amplification, distribution, and output of satellite signals in the eight-output novel KU-band LNB PC board circuit structure.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
