The invention discloses a strip line nonreciprocal knot assembly for a circulator. A nonreciprocal knot is formed by a strip line between two ferrite spiral magnetic sheets and the ferrite spiral magnetic sheets. The strip line nonreciprocal knot assembly comprises a center circular knob assembly (1), a Y-shaped knot assembly (2) and at least three port ends (3). The Y-shaped knot assembly (2) and the three port ends (3) are distributed on the center circular knob assembly (1) at intervals; a parallel inductor is formed by the Y-shaped knot assembly (2); capacitors are formed at outlets of the port ends (3); and the inductor and the capacitors form LC (inductor-capacitor) matching sections. According to the strip line nonreciprocal knot assembly for the circulator provided by the invention, the nonreciprocal knot is formed by the strip line among two ferrite spiral magnetic sheets and the ferrite spiral magnetic sheets; and the capacitor formed at the port ends and the parallel inductor formed by the Y-shaped knot assembly form the LC matching sections, so that the circuit matching is realized through the LC matching sections. The strip line nonreciprocal knot assembly has no need of further arranging a connection device, has the advantages of not only reducing the equipment cost but also improving the security, prolonging the service life of the device, and the like.
Description
technical field [0001] The present invention relates to a circulator stripline non-reciprocal junction assembly. Background technique [0002] The circulator is a multi-port device that transmits the incident wave entering any port to the next port in sequence according to the direction determined by the static bias magnetic field. The strip line between the gyromagnetic pieces and the structure between the gyromagnetic pieces are one of the important indicators that affect the size and performance of the circulator. In the prior art, the connecting devices are mostly used directly, and the connecting devices need to occupy a certain space. When designing, it is necessary to reserve a certain space for it, and it is easy to interact with adjacent devices, and the safety factor is low. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a circulator strip line non-reciprocal junction assembly,...
