Abstract

The present application relates to a phase shifter, a millimeter wave circulator and a radar system, wherein the phase shifter includes a housing, a waveguide, a ferrite, a first magnet, a second magnet and a cooling channel. The housing defines an accommodating space; the waveguide is arranged in the accommodating space; the ferrite is attached to the inner wall of the waveguide; the first magnet is located in the accommodating space, and is arranged in a close fit On the outer wall of the waveguide, the first magnet and the housing define a first cavity; the second magnet is located in the accommodation space and is attached to the outer wall of the waveguide, the first magnet Two magnets are arranged opposite to the first magnet, and the second magnet and the housing define a second cavity; the cooling channel is opened in the housing, and the cooling channel is used to pass through the first a cavity and the second cavity. The phase shifter, millimeter wave circulator and radar system provided by the application have good cooling effect, high power and low loss.

Description

technical field [0001] The present application relates to the field of microwave technology, in particular to a phase shifter, a millimeter wave circulator and a radar system. Background technique [0002] With the continuous development of aerospace, electronic countermeasures and other technical fields, microwave systems have higher and higher requirements for ferrite devices. Miniaturization, broadband, high power and low loss have become the key research directions of ferrite devices. [0003] The millimeter wave circulator is an important type of ferrite device. Millimeter-wave circulators are widely used in millimeter-wave radar systems. The millimeter-wave circulator is mainly used to control the unidirectional transmission of energy in the loop. It is generally used as a radar transceiver switch and plays a protective role in the antenna feeder and transmitter in the radar system. [0004] A millimeter-wave circulator generally consists of a bridge, a folded doubl...
