Claim 8:
9. The multiplexer as claimed in claim 7, further comprising:
a first inductor coupled between the first signal input terminal and a first node;
a first switch coupled between the first node and a second node;
a second inductor coupled between the second node and the first signal output terminal;
a second switch coupled between the voltage source terminal and a third node;
a first resistor coupled between the third node and the second node;
a third inductor coupled between the second signal input terminal and a fourth node;
a third switch coupled between the fourth node and the second node;
wherein the first amplifier has a first input terminal coupled to the first node, and a first output terminal coupled to the first signal output terminal;
wherein the second amplifier has a first input terminal coupled to the fourth node, and a first output terminal coupled to the first signal output terminal,
wherein in response to the multiplexer operating simultaneously at the first selection state and at the first transmission mode, the first switch is turned on, the second and third switches are turned off, the first and second amplifiers are disabled, and the first inductor, the first switch, and the second inductor are in the first signal transmission path, and
wherein in response to the multiplexer operating simultaneously at the second selection state and at the first transmission mode, the first and second switches are turned off, the third switch is turned on, the first and second amplifiers are disabled, and the third inductor, the third switch, and the second inductor are in the second signal transmission path.
