Abstract

The invention provides a surface-mounted microstrip circulator, which adopts a gyromagnetic ferrite with high polishing degree as a substrate, adopts a microstrip circuit as a circuit signal transmission layer, and replaces a traditional surface-mounted strip line structure. Compared with a traditional surface-mounted microstrip circulator with the strip line structure, the miniaturized surface-mounted microstrip circulator has the characteristics of light weight, small size, simple structure, high reliability and convenient installation and use. The product is stable in high temperature (-65 DEG C to 125 DEG C) and convenient to install, and the service life of the product can reach 40000 hours at most in a working environment of 85 DEG C. Compared with the existing circulator, the circulator provided by the invention has the advantages of more reliable performance, simpler structure, more convenient installation mode and more excellent temperature adaptability, and is more suitable for various large-scale automatic production microwave circuits.
