Abstract

The invention discloses an assembling and debugging method for improving the producibility of a high-frequency coaxial circulator / isolator, and the method comprises the steps of enabling a substrate and a central conductor to form a unit group in sequence through employing a positioning clamp, enabling the substrate and the central conductor in each unit group to be coaxial, and enabling each unitgroup to be coaxial; bonding and shaping the unit groups; preparing a cavity, and arranging debugging holes at the positions, corresponding to three ports, of the cavity; assembling a product and connecting to a vector network analyzer, and injecting silicone rubber in the debugging holes to adjust the circuit matching, thereby improving the performance parameters of the device. According to thepresent invention, by combining the improvement of a sheet arrangement process, forming the debugging holes at the corresponding positions of the cavity, and utilizing the high consistency of the sheet arrangement unit groups and the high consistency of the cavity structure, the method for improving the assembly speed and debugging the product performance without opening the cavity is provided. The producibility increase of the high-frequency coaxial circulator / isolator can be greatly promoted, so that single products have high consistency and high debugging efficiency, and the requirement oflarge-batch production is met.

Description

technical field [0001] The invention relates to an assembly and debugging method, in particular to an assembly and debugging method for improving the productivity of a high-frequency coaxial circulator / isolator. Background technique [0002] With the development of microwave technology, K-band and above frequency bands are widely used in communication, electronic countermeasures and radar because of their miniaturization, wide frequency band characteristics, good penetration and confidentiality. With the development of the microwave complete system in the K-band and above frequency bands, the demand for high-frequency coaxial circulators / isolators is also increasing. In order to meet the large-scale needs of the complete system, high-frequency coaxial Isolators place new demands in terms of ease of manufacturability, high consistency, and fast debug methods. [0003] The traditional high-frequency coaxial circulator / isolator is difficult to meet the mass production requirem...
