Claim 11:
12. A radio frequency circuit, comprising:
a substrate;
a first conducting wire disposed on a first surface of the substrate;
a second conducting wire disposed on the first surface and arranged corresponding to the first conducting wire; and
four transmission lines, wherein two of the four transmission lines are respectively connected to two ends of the first conducting wire to form an input part and an output part, and another two of the four transmission lines are respectively connected to two ends of the second conducting wire to form a coupling part and an isolation part, wherein the input part is arranged corresponding to the coupling part, the output part is arranged corresponding to the isolation part, and the isolation part is connected to a ground potential;
wherein the first conducting wire and the second conducting wire are separate from each other and coupling to each other, and each of a width of the first conducting wire and a width of the second conducting wire is not equal to a width of any one of the four transmission lines.
