Zusammenfassung:A front-end circuit for a wireless communication system includes a first amplifier, a second amplifier and an antenna switch. The first amplifier is disposed at a receiving path, wherein the first amplifier has an input terminal and an output terminal, and the input terminal of the first amplifier is coupled to a first pad. The second amplifier is disposed at a transmission path, wherein the second amplifier has an input terminal and an output terminal, and the output terminal of the second amplifier is coupled to a second pad different from the first pad. The antenna switch is coupled between the input terminal of the first amplifier and the output terminal of the second amplifier.
