Abstract

The embodiment of the invention provides a circuit system, comprising N sections of transmission lines, wherein N is larger than or equal to 2; the N sections of transmission lines have M different impedances and M is larger than or equal to 2 and is smaller than or equal to N; the M different impedances meet the preset function relation and correspond to M transmission lines with different line widths; in the transmission lines with M different impedances, copper lines are arranged at two sides of the transmission lines with the low impedances, and the copper lines are grounded; the transmission lines with the low impedances and the copper lines arranged at two sides of the transmission lines with the low impedances form a coplanar wave guide structure, so the influence of the line width error on the coupling degree of the transmission lines with the low impedances and the influence of the line width error on the coupling degree of the transmission lines with the high impedances can be mutually offset.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a circuit system. Background technique [0002] In the production process of Printed Circuit Board (referred to as PCB), over-etching or under-etching will occur in the line width processing of the circuit system on the PCB, and the error is generally ±2mil (mil). When the transmission line is a thin line, since the impedance of the transmission line is greatly affected by the change of the line width, when there is an error in line width processing, the coupling performance of the circuit system will deteriorate due to the low tolerance performance of the circuit system, resulting in The processing error performance has become the bottleneck of the batch application of the circuit system. [0003] In the prior art, in view of the impact of processing errors on the performance of the circuit system, in the process of making the PCB, the radiation patch of t...
