Embodiment Construction
[0031]In the embodiment described below, the negative group delay circuit based on the ferrite circulator includes: including: N input ports, and N output ports corresponding to the N input ports, a ferrite with M ports Circulator and matching load, N signal input ports of negative group delay circuit and N output ports of ferrite circulator are connected with N input ports of ferrite circulator, ferrite circulator with n working modes The remaining P ports except the input and output ports are connected to matching loads; the N-way signals of the negative group delay circuit are respectively input from the N input ports of the circuit and output from the corresponding N output ports to generate N-way negative group time delay. The direction of the DC bias magnetic field in the ferrite circulator is perpendicular to the plane of the ring signal generated by it; the signal flow direction of the signal entering the signal input port of the negative group delay circuit is opposit...
