Multi-frequency-point multi-working-mode dual-circular-polarization microwave network

The invention provides a multi-frequency-point multi-working-mode dual-circular-polarization microwave network, which comprises an antenna feed source, a circular polarizer, a left-hand polarization conversion channel, a right-hand polarization conversion channel and a circulator, wherein the left-hand polarization conversion channel and the right-hand polarization conversion channel are respectively connected with the circular polarizer, and the circulator is connected with the left-hand polarization conversion channel. The filter is connected with the two ports of the circulator and the right-handed polarization conversion channel; the low-noise amplifier and the power amplifier are respectively connected with the filter; the working mode comprises a same-frequency transmitting-receiving time-sharing working mode and a different-frequency transmitting-receiving simultaneous working mode. According to the invention, integration of a same-frequency time-sharing transceiving half-duplex working mode and a pilo
