A filtering device, an antenna switch module and a dual-mode terminal. The filtering device at least includes a duplexer configured for the same frequency band of a first mode signal and a second mode signal. The duplexer is used for receiving the first mode signal and the second mode signal in a manner of time division multiplexing and filtering the received signals and outputting same. The filtering device and a dual-mode terminal having same can reduce the number of chips in use, thereby reducing the occupied PCB area, improving the integration degree of the radio frequency circuit of the dual-mode terminal, which is advantageous for realizing miniaturization of the terminals and advantageous for reducing hardware costs. |
