Abstract

The invention provides a miniature waveguide mode circulator which comprises an upper shell, a lower shell, a Y-shaped junction waveguide and ferrite elements, wherein permanent magnets are arranged on the upper shell and the lower shell, a waveguide impedance transformer is arranged on a wide-edge plane of the Y-shaped junction waveguide, and the two ferrite elements are positioned on a center axle line of the waveguide impedance transformer and the permanent magnets; metal electromagnetic conductors are placed into the Y-shaped junction waveguide and connected with the corresponding edge of the Y-shaped junction waveguide, the width of a port of the Y-shaped junction waveguide is less than the half-wavelength of a working frequency, the metal electromagnetic conductors extend from a Y-shaped junction plane of the Y-shaped junction waveguide and are mutually isolated; and at least one microwave absorber element is arranged at two sides of each metal electromagnetic conductor and used for absorbing a reflection power of the port. The miniature waveguide mode circulator is in a structure of matching a waveguide thin stick with a terminal load, is suitable for miniature waveguide isolator elements, has the advantages of small total size, light weight and ideal isolation property, and is used for filtering a high-order mode by adopting a combination mode of a plurality of waveguide isolators.

Description

technical field [0001] The invention relates to a microwave ferrite device, in particular to a waveguide type circulator / isolator. Background technique [0002] The three-port microwave ferrite junction circulator, also known as the Y-junction circulator, is one of the most commonly used junction circulators. Signal isolation (inhibition). A typical waveguide junction circulator / isolator includes a defined waveguide structure, at least one waveguide impedance transformer, and a ferrite material is installed on its upper part, which is biased by a magnetic circuit system to produce an ideal non-reciprocal effect . By controlling the direction of the bias magnetic field of the magnetic circuit system, the circular direction of the signal (clockwise or counterclockwise) can be changed. [0003] US Patent No. 3,851,279 discloses an improved broadband Y-junction waveguide circulator. The Y-junction region of the two waveguides is a ferrite element, and its cross section is tri...
