Description

technical field [0001] The present application relates to the technical field of high-frequency switches, and in particular, to a ferrite switch, a microwave antenna and an electronic device. Background technique [0002] With the increase of data traffic, wireless base stations / microwave macro base stations need to meet larger 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 frequency bands, have more abundant spectrum resources, but the development of supporting high-frequency devices is not mature, which makes the bandwidth, insertion loss and Indicators such as reciprocity will influence 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 correspondence between the multipl...
