Zusammenfassung:The utility model discloses a P wave band high intermodulation broadband circulator/isolator under the size of one inch, which comprises a central conductor, the upper surface and the lower surface of the central conductor are respectively provided with a ferrite, the side wall of each ferrite is sleeved with a ceramic dielectric ring, and the central conductor comprises a central junction and three matching circuits. The matching circuit comprises an inductance type transmission line, a capacitance type transmission line and a microwave transmission line. According to the utility model, the radius of the central junction is larger than that of the ferrite, and the projection of the ferrite on the horizontal plane is located in the projection area of the central junction on the horizontal plane, so that the intermodulation performance can be effectively improved, and the intermodulation performance can be improved by nearly 60%; the inductance type transmission line is arranged along the peripheral direction
