Claim 10:
11. The multiplexer as claimed in claim 9, further comprising:
a third signal input terminal;
a fourth signal input terminal; and
a second signal output terminal;
wherein the path circuit is further coupled between the third and fourth signal input terminals and the second signal output terminal and further comprises:
a fourth inductor coupled between the third signal input terminal and a fifth node;
a fourth switch coupled between the fifth node and a sixth node;
a fifth inductor coupled between the sixth node and the second signal output terminal;
a fifth switch coupled between the voltage source terminal and a seventh node;
a second resistor coupled between the seventh node and the sixth node,
a sixth inductor coupled between the fourth signal input terminal an eighth node;
a sixth switch coupled between the eighth node and the sixth node;
wherein the first amplifier further has a second input terminal coupled to the fifth node and a second output terminal coupled to the second signal output terminal,
wherein the second amplifier further has a second input terminal coupled to the eighth node and a second output terminal coupled to the second signal output terminal,
wherein in response to the multiplexer operating simultaneously at the first selection state and at the first transmission mode, the fourth switch is turned on, and the fifth and sixth switches are turned off, and
wherein in response to the multiplexer operating simultaneously at the second selection state and at the first transmission mode, the fourth and fifth switches are turned off, and the sixth switch is turned on.
