<p>Disclosed is a matching circuit. The matching circuit comprises an isolation module, a filtering module, and a matching module. The filtering module is connected between the isolation module and the matching module. The isolation module is used for isolating signals not having a specified frequency, and transmitting a signal of the specified frequency. The filtering module is used for filtering out signals not having the specified frequency. The matching module is used for performing matching on the signal of the specified frequency. Correspondingly, also disclosed are a matching circuit network and a signal transceiver device. The complexity of the signal transceiver device can be decreased, the costs can be decreased, and the hardware resources can be conserved; furthermore, the problem of the incapability in receiving signals of multiple paths at the same time in a situation that an antenna switch is used in the prior art is solved, and the signal receiving efficiency is improved.</p> |
