This article is devoted to the solution of actual problem to increase productivity and accuracy of adjusting works in production, and safety precautions observance by manufacture, repair and options attenuators, built in measuring instruments of increased capacity. The aim of the work is to develop automated method to adjust SWRU and uneven frequency response in microwave attenuator. This article offers theoretical analysis of the offered model of microwave attenuator representing the system of adjustment block, controlled by computer and the block setting the values of standing wave ratio on voltage (SWRU) and attenuator transfer factor. The article describes the method to implement a given model representing a directed system made of attenuators and automatic adjustment node as well as the results of offered sample research. Also applied importance of technical application for the developed device to adjust standing wave ratio on voltage SWRU in microwave attenuators is considered.
Key words: standing wave ratio on voltage, amplitude-frequency characteristic non-uniformity, microwave attenuators, waveguide, electromagnetic wave, microstrip line, inductance, capacity, resistor, dielectric substrate.
