Automatic filter debugging device

Abstract

The invention relates to an automatic filter debugging device comprising a vector network analyzer, a computer, and a motor controller. The vector network analyzer is connected with the output end of a target filter. The input end of the computer is connected with the output end of the vector network analyzer, and the output end of the computer is connected with the motor controller. The output end of the motor controller is connected with the target filter through a motor. The vector network analyzer is used for reading the S parameter of the target filter. The computer calculates a corresponding filter coupling matrix according to the S parameter, compares the coupling matrix with an ideal coupling matrix to get an error matrix, calculates the regulation quantity of the filter according to the error matrix, and sends the regulation quantity to the motor controller. The motor controller outputs a signal to debug the corresponding filter according to the regulation quantity. Full-automatic filter debugging is realized. The efficiency of filter debugging is improved greatly. The cost of personnel and equipment needed for traditional debugging is reduced. The consistency of products is ensured to the maximum.

Description

technical field [0001] The invention relates to microwave communication, in particular to filter debugging equipment in communication. Background technique [0002] A filter is a device used to eliminate interference noise, and the input or output is filtered to obtain the communication band required by the device. The main function of the filter is to effectively filter out the frequency point of a specific frequency or the frequency other than the frequency point. In a communication base station, a filter is an essential radio frequency device. In 2014, there were about 8 mainstream filter manufacturers in China, most of which were large listed companies, with a total output of about 4 million pieces. [0003] In the current production process of filters at home and abroad, the filter debugging link has become an important factor that plagues the efficiency and cost of all filter manufacturers, because there is currently no mature automation equipment used in this debugg...

Problems solved by technology

Because of the use of large-scale manual debugging, there are four main development constraints on the enterprise. First, the skill proficiency of employees directly determines the production efficiency; second, because it is completely dependent on manual debugging of employees, how to retain Experienced employees, high salary expenditures are also problems faced by enterprises; third, due to the complete reliance on manual debugging, and the skill levels of each employee are different, the product consistency is poor, which directly affects the pass rate of back-end tests and customers. Repair rate; Fourth, due to large-scale manual debugging, the test platform of each debugging employee will bring high investment in hardware equipment, which will be a huge challenge to enterprise cost control
