Satellite signal transceiving and radio frequency distribution circuit and satellite receiving system

The utility model discloses a satellite signal transceiving and radio frequency distribution circuit and a satellite receiving system. The satellite signal transceiving and radio frequency distribution circuit comprises three power dividers, wherein the first power divider is connected with a receiving channel and a transmitting channel of a radio frequency signal, and transmits the radio frequency signal of the transmitting channel to the antenna through power distribution and synthesis, or transmits the radio frequency signal received by the antenna to the receiving channel; the second power divider divides the receiving channel into two channels, one channel forms a local receiving channel for transmitting a received radio frequency signal, and the other channel forms a radio frequency distribution channel; and the third power divider divides the radio frequency signal transmitted by the radio frequency distribution channel into two paths to form two paths of radio frequency distribution signals.
