Method, device and calibration device for determining transmission line standard device

Abstract

The invention discloses a method and equipment for determining a transmission line standard device and calibration equipment. The method comprises the steps of determining a to-be-calibrated band of to-be-calibrated equipment; selecting a first frequency in the to-be-calibrated band, and calculating a channel combine corresponding to the first frequency; determining the thickness of the transmission line standard device corresponding to the to-be-calibrated band according to a set phase change interval and the channel combine corresponding to the first frequency; and determining the transmission line standard device according to the thickness. The thickness of the transmission line standard device is determined according to the set phase change interval and the channel combine corresponding to the first frequency included in the to-be-calibrated band, and the transmission line standard device is determined based on the determined thickness, so that the thickness of the determined transmission line standard device is obviously increased, and the problem of low accuracy of calibration on a vector network analyzer with a TRL (Transistor Resistor Logic) method due to deformation of the transmission line standard device can be effectively solved.

Description

technical field [0001] The invention relates to the field of calibration of vector network analyzers, in particular to a method, equipment and calibration equipment for determining transmission line standard components. Background technique [0002] Vector network analyzer (English name: vector network analyzer) is a test equipment for electromagnetic wave energy, which can be used to measure the microwave network characteristics of microwave devices such as microwave amplifiers, attenuators, and isolators. Usually, the vector network analyzer has certain systematic errors. Therefore, in order to ensure the accuracy of the microwave test results, it is necessary to calibrate the vector network analyzer before using it. [0003] In the millimeter wave frequency band, the TRL method with higher accuracy is usually used to calibrate the vector network analyzer. Before using the TRL method to calibrate the vector network analyzer, it is necessary to make a TRL calibration devic...
