Broadband satellite feed link receiving channel system

The invention relates to a broadband satellite feed link receiving channel system, which comprises a low-noise amplification module, a shunt module and a frequency conversion module, the low-noise amplification module is used for carrying out amplification processing on an uplink signal of the feed link; the shunt module is used for dividing the amplified signal into multiple paths of signals; the frequency conversion module is connected with the plurality of signal processing terminals and is used for performing frequency conversion on the multiple paths of signals and correspondingly inputting the signals subjected to frequency conversion into the plurality of input terminals; and the frequency conversion module is also used for switching the corresponding relationship between the multiple paths of signals and the multiple signal processing terminals. According to the feed link receiving channel disclosed by the invention, a mode of performing frequency and path planning configuration in orbit is adopted ba
