Abstract

PURPOSE:To attain miniaturization of a strip line type circulator by arranging a permanent magnet generating a DC magnetic field to the peripheral of a garnet. CONSTITUTION:A strip line 7 clipped by the two garnet discs 6 and a doughnut type aluminum board 8 at the peripheral of the garnet discs 6 are arranged, three circular arc type permanent magnets 10 are arranged between the peripheral part and the strip line 7 and a cover and yoke 11 cover the upper face. The cover and yoke 11 is provided with a projection 13 so that the magnetic flux is converged to the garnets 6. Further, a projection 14 is provided to a part in contact with the garnets 6 of a lower case and yoke 12. Thus, the height of the entire circulator is decreased much and the structure with less waste of volume is selected.

Circulation regulators, which are the most important component of microwave equipment, are used in a wide range of microwave fields for purposes such as matching between protection stages of transistors during high-power operation and eliminating unnecessary radiation. Recently, with the rapid miniaturization of other microwave elements, the space occupied by the circulator in the entire microwave apparatus has become quite noticeable. Furthermore, from the perspective of the overall cost of the K-microphone four-wave device, the price of the K-microwave generator occupies a considerable portion. Therefore, miniaturization of the circuit regulator,
The demand for lower prices is only getting stronger day by day. The present invention relates to an improvement in the structure of a circuit rotor in order to meet the industrial demands for downsizing and low cost.

In the conventional structure, a permanent magnet is placed above or below the garnet, and the magnitude of the DC magnetic field is closely related to the operating frequency of the circulator, making it possible to create a circulator that operates at high frequencies. This requires a high magnetic field, and conventional structures necessarily require the use of large permanent magnets. Therefore, in the conventional structure, the volume of the permanent magnet is extremely large, and the circierator as a whole has a large height dimension and a wasteful structure in terms of volume.
