Claim 17:
18. The multiplexer as claimed in claim 16, further comprising:
a second signal input terminal;
a third signal output terminal; and
a fourth signal output terminal;
wherein the path circuit is further coupled between the second signal input terminal and the third and fourth signal output terminals and further comprises:
a fourth inductor coupled between the second signal input terminal and a sixth node;
a fifth switch coupled between the sixth node and a seventh node;
a fifth inductor coupled between the seventh node and the third signal output terminal;
a sixth switch coupled between the voltage source terminal and an eighth node;
a third resistor coupled between the eighth node and the seventh node,
a sixth switch coupled between the sixth node and a ninth node;
a sixth inductor coupled between the ninth node and the fourth signal output terminal;
an eight switch coupled between the voltage source terminal and a tenth node;
a fourth resistor coupled between the tenth node and the ninth node;
wherein the first amplifier further has a second input terminal coupled to the sixth node and a second output terminal coupled to the third signal output terminal,
wherein the second amplifier further has a second input terminal (coupled to the sixth node and a second output terminal coupled to the fourth signal output terminal,
wherein in response to the multiplexer operating simultaneously at the first selection state and at the first transmission mode, the fifth switch is turned on, and the sixth, seventh, and eighth 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 fifth, sixth, and eight switches are turned off, and the seventh switch is turned on.
