Claim 11:
12. The balance-unbalance conversion apparatus according to claim 1, wherein:
the first balance signal connecting section comprises a first parallel section and a first tilt section, wherein the first parallel section is configured to transmit the first component of the balance signal, one end of the first tilt section is connected to the first parallel section, and the other end of the first tilt section is connected to the first impedance matching section;
the second balance signal connecting section comprises a second parallel section, wherein the second microstrip further comprises an impedance transition section, the impedance transition section and the second impedance matching section are located on a same plane, one end of the impedance transition section is connected to the second parallel section through a via, and the other end of the impedance transition section is connected to the second impedance matching section;
the conductive ground comprises a first reference ground, wherein the first reference ground is a reference ground of the first parallel section and the second parallel section; and
impedance formed by the first tilt section and the impedance transition section remains unchanged and is the same as impedance formed by the first parallel section, the second parallel section, and the first reference ground, or
impedance formed by the first tilt section and the impedance transition section has a gradient, so that a smooth transition from the impedance formed by the first parallel section, the second parallel section, and the first reference ground to the impedance formed by the unbalance signal connecting section and the ground section is implemented.
