The ferrite switch comprises a coupler, a first magic T and two ferrite circulators, each ferrite circulator is provided with a first port, a second port and a third port, the second port is connected with a short-circuit load, and the first ports of the two ferrite circulators are respectively connected with the two output ports of the coupler; the two output ports of the coupler are used for outputting power signals with equal amplitude, same phase or equal amplitude and opposite phase, the third ports of the two ferrite circulators are connected with the two input ports of the first magic T respectively, and the power signals with equal amplitude, same phase and equal amplitude and opposite phase are input from the two input ports of the first magic T, and then are respectively output from the two output ports of the first magic T. The embodiment of the invention provides a ferrite switch, a microwave antenna and electronic equipment, and aims to solve the problems of complex structure and high insertion loss of a reciprocal ferrite switch.

Description

technical field [0001] The present application relates to the technical field of high-frequency switches, in particular to a ferrite switch, a microwave antenna and electronic equipment. Background technique [0002] With the increase of data traffic, wireless base stations / microwave macro stations need to meet greater communication capacity requirements, but spectrum bandwidth has gradually become a bottleneck for capacity improvement. High frequencies, such as microwaves in the E-Band or D-Band bands, have more abundant spectrum resources, but the development of supporting high-frequency devices is not yet mature, making some high-frequency devices, such as the bandwidth, insertion loss and Indexes such as reciprocity will determine the performance of high-frequency communication systems. [0003] The high-frequency switch includes a ferrite switch. The ferrite switch has multiple ports. By changing the external magnetization state and controlling the corresponding relati...
