Abstract: A radio-frequency front-end module includes a common node, a first node, a second node, a third node, a first path, a second path and a third path. The first path may be disposed between the common node and the first node and may include an inductor. The second path may be disposed between the common node and the second node and may include a second switch. The third path may be disposed between the common node and the third node and include a third switch. When the second switch is turned on, the second path may transceive the second signal and the third switch may be turned off, such that the inductor in the first path may provide an inductive impedance for the second signal, and the third switch may provide a capacitive impedance for the second signal.

Abstract: A front end module includes a first radio frequency (RF) terminal, a second RF terminal, a third RF terminal, a transmission path and a reception path. The transmission path is formed between the first RF terminal and the third RF terminal. The reception path is formed between the first RF terminal and the second RF terminal. The reception path includes a first set of switches, a second set of switches, a third set of switches and an amplifier. An amplifier is coupled to the second set of switches and the second RF terminal. The third set of switches is coupled to the first set of switches and the second RF terminal. When a transmission signal is transmitted to the first RF terminal via the transmission path, the first set of switches, the second set of switches and the third set of switches are turned off.
