Problems solved by technology

The disadvantage of this method is that the repeated connection and disconnection of the cable will introduce repeatability errors, and only the parameters including the fixture can be obtained, not the scattering parameters of the transmission line itself

Abstract

The invention relates to a four-port apparatus for measuring microstrip transmission line network crosstalk, which is characterized in that including a vector network analyzer, which includes a data terminal and two signal terminals, wherein the two signal terminals are connected to a coaxial cable separately; a plurality of coaxial standards, which cooperate with the signal terminals of the vector network analyzer for splicing and measuring circuit; a digital signal processor, which is connected to the data terminal of the vector network analyzer through a data line, and receives the measured data of the vector network analyzer to calculate.

Description

technical field [0001] The invention belongs to the field of microwave circuit measurement, and more specifically relates to a four-port microstrip transmission line network crosstalk measurement device, which can measure all scattering parameters of high-frequency microstrip circuits, especially parameters representing crosstalk and coupling. Background technique [0002] The design of integrated circuits is developing towards high frequency, small size, and multiple components, which leads to more and more crosstalk between components and transmission lines inside the circuit, which seriously restricts the development of integrated circuits. Correspondingly, how to measure and characterize it is also a practical task faced by circuit design and application. [0003] The error measurement models of vector network analyzers commonly used at present, such as the eight-term model and the twelve-term model, do not have an error term that characterizes crosstalk. The actual circ...
