Abstract (en)
[origin: EP4120469A1] This application provides a ferrite switch, a microwave antenna, and an electronic device. The ferrite switch includes a coupler, a first magic T, and two ferrite circulators. The ferrite circulators have first ports, second ports, and third ports, the second ports are connected to short-circuit loads, the first ports of the two ferrite circulators are respectively connected to two output ports of the coupler, the two output ports of the coupler are configured to output equi-amplitude in-phase or equi-amplitude phase-inverted power signals, and the third ports of the two ferrite circulators are respectively connected to two input ports of the first magic T; and after the equi-amplitude in-phase or equi-amplitude phase-inverted power signals are input from the two input ports of the first magic T, the power signals are output from two output ports of the first magic T respectively. Embodiments of this application provide a ferrite switch, a microwave antenna, and an electronic device, to resolve problems of a complicated structure and a high insertion loss of a reciprocal ferrite switch.
