[0041] The RF front-end unit is used to convert 5G radio waves in space into processable RF signals, including antennas, low-noise amplifiers and filters. In this embodiment, the antenna selects the corresponding antenna topology according to the 5G frequency band, and optimizes the antenna geometric parameters, including size, shape, and feeding method, to achieve broadband, high efficiency, and good directivity. The low-noise amplifier uses a low-noise amplifier chip GaAsHEMT, and achieves broadband, low-noise, and high-linearity amplification performance through a passive matching network, and uses feedback and bias circuit technology to stabilize the operating point of the amplifier. The filter uses a high-Q SAW filter, and uses the adjustment of the resonant frequency of the SAW filter to achieve tunable filtering characteristics, and achieves higher selectivity through series-parallel multi-stage filters.

[0042] The down-conversion unit is used to convert the radio frequency signal to a lower intermediate frequency signal, thereby achieving wide-band, low-noise, and high-dynamic range performance indicators. In this embodiment, the down-conversion unit includes a mixer, a local oscillator source, and an intermediate frequency amplifier. The mixer adopts a duplex mixer topology, uses a power distribution network and phase detection technology to achieve high linearity, and uses low-noise transistors and optimized circuit layout to reduce noise. The local oscillator source uses frequency synthesis technology to generate a local oscillation signal with a wide frequency range and high stability, and adopts a frequency division and frequency multiplication hybrid topology to achieve flexible frequency adjustment. It combines phase locking and voltage-controlled crystal oscillator circuits to achieve low phase noise and stable frequency. The intermediate frequency amplifier adopts a low-noise, high-gain amplifier chip SiGeHBT, optimizes the linearity and stability of the amplifier through feedback and bias circuits, and uses a filter network to achieve bandpass filtering of the intermediate frequency signal. A multi-stage down-conversion architecture is adopted to gradually reduce the signal frequency, filter in the intermediate frequency band, reduce the sampling rate requirements of subsequent analog-to-digital conversion, and use I / Q demodulation technology to obtain the complex envelope signals of the real and imaginary parts.

[0043] The digital signal processing unit is used to digitally filter, amplify, and correct the intermediate frequency signal after down-conversion, so as to ensure that the signal quality meets the 5G standard requirements.
