Multiplexer

摘要

A multiplexer is disclosed configured between a transceiving antenna and a receiving channel and a transmitting channel; the transceiving antenna, the receiving channel and the transmitting channel are shared by signals of at least two modes. The multiplexer includes a combiner module, transmitting filter modules, receiving filter modules and amplifier modules in one-to-one correspondence with the signals of various modes. The multiplexer addresses the problem of how multi-mode signals share a transmitting channel, a receiving channel and a transceiving antenna.

1. A multiplexer, set between a transceiving antenna and a receiving channel as well as a transmitting channel; wherein the transceiving antenna, the receiving channel and the transmitting channel are shared by signals of at least two modes, the multiplexer comprises:
a combiner module, as well as transmitting filter modules, receiving filter modules and amplifier modules in one-to-one correspondence with the signals of various modes; wherein each transmitting filter module is configured to select a signal of a corresponding mode from signals to be transmitted through the transmitting channel, and transmit the signal of the corresponding mode to the transceiving antenna; each receiving filter module is configured to select a signal of a corresponding mode from signals received by the transceiving antenna, and transmit the signal of the corresponding mode to the amplifier module connected thereto; each amplifier module is configured to amplify the signal of the corresponding mode selected by the receiving filterer module connected thereto and transmit the signal of the corresponding mode to the combiner module; the combiner module is configured to receive signals amplified by each amplifier module, performs combination processing on the signals, and transmit the combined signal to the receiving channel.
