<p>A dual-mode radio frequency tranceiving device, a filtering device and a dual-mode terminal. The dual-mode radio frequency tranceiving device at least includes a low noise amplifier (LNA) configured for the same frequency band of a first mode signal and a second mode signal. The LNA is used for receiving signals of the corresponding frequency bands of the first mode signal and the second mode signal in a manner of time division multiplexing and amplifying the received signals and outputting same. Since the LNA is a multiplexing LNA, the number of LNAs in the dual-mode radio frequency tranceiving device is reduced, the dual-mode radio frequency tranceiving device can be integrated to a greater extent, increasing the layout space, so that the integration degree of a dual-mode terminal including the dual-mode radio frequency tranceiving device is higher, which is more advantageous for realizing miniaturization of terminals.</p> |
