LOW TEMPERATURE RESISTANT MICROWAVE FERRITE CIRCULATOR

摘要

The present invention relates to a low temperature resistant microwave ferrite circulator, comprising an upper end cover and a lower end cover which are provided opposite to each other. A first groove is provided on one side of the upper end cover back to the lower end cover, a second groove is provided on one side facing the lower end cover, a third groove is provided on one side of the lower end cover facing the upper end cover, and a fourth groove is provided on one side back to the upper end cover. A first magnet is provided in the first groove, a first medium ring and a ferrite are provided in the second groove, a second medium ring and a ferrite are provided in the third groove, a fourth magnet is provided in the fourth groove, and an inner conductor is provided between the first medium ring and the second medium ring. According to the circulator, the grooves are provided on two sides of the end covers, and the magnets and the ferrites are provided in the grooves on the two sides, then the inner conductor is provided between the two ferrites, and the geometric length of an output segment of the inner conductor is shortened, thereby reducing the volume of a device. By using a ferrite mixed with a special material, the device can be operated at an extreme low temperature environment of -270°C.
