Problems solved by technology

However, due to the processing limitations of the one-piece housing design, to match the asymmetric shape of the converter at the 3-port junction, the converter must be processed separately and pasted into the one-piece housing with a low-loss adhesive

Embodiment Construction

[0023] Three-port waveguide junction circulator / isolator with rectangular transformers, one-piece housing with multiple ports, waveguide junctions with asymmetrically shaped transformers relative to the ports, ferrite elements placed on the transformers, ferrite The bulk element is symmetrical with respect to each port of the waveguide junction.

[0024] Such as figure 1 As shown, the housing of the waveguide junction circulator or isolator is made into a single-piece housing 40, and the single-piece housing 40 is made of a single-piece body, and the converter 41 is processed together as a part of the housing. For the circulator or isolator As far as the ports are concerned, the transducers 41 are machined asymmetrically in the single-piece housing 40, while the ferrite elements 42 are machined in symmetrical form (using a CNC machine) corresponding to the corresponding ports. In addition, the housing is a composite, and in this one-piece housing, the transformer 41 is asymme...

Abstract

The invention provides a three-port waveguide junction circulator / isolator and a manufacturing method thereof, the three-port waveguide junction circulator / isolator comprises a single-piece housing with multiple ports and a waveguide junction of a converter in an asymmetric shape relative to the ports, a ferrite element is placed on the converter, and the ferrite element is symmetric relative to all the ports of the waveguide junction. The waveguide junction circulator / isolator comprises the asymmetric rectangular converter relative to the three ports of the junction, and the converter is easy to process integrally as a component part of the single-piece housing of the waveguide junction circulator / isolator, thereby significantly reducing the processing cost of materials and the production and manufacturing cost of the waveguide junction circulator / isolator.

Description

technical field [0001] The invention relates to a waveguide circulator / isolator, in particular to a three-port waveguide junction circulator / isolator with a rectangular transformer and a manufacturing method thereof. Background technique [0002] A typical metal mechanism waveguide junction circulator or isolator, the center of the structure contains three intersecting coplanar waveguides to form a waveguide junction, and a triangular ferrite block is placed in the center of the waveguide junction and above the converter , and the bias cross-sectional magnetic field is provided by two constant magnets. [0003] The transformer is used to match the impedance of the waveguide and ferrite. In the most typical waveguide circulator / isolator, the transformer is made into a cylinder or triangle according to the shape of the ferrite, which is used in the waveguide junction circulator / isolation in order to obtain the best match from the waveguide section to the ferrite ring junction...
