| Sumario: | The need to reduce cost and space in the manufacture of electronic equipment in printed circuit boards that conform the devices, has generated that the transmission lines that interconnect them are manufactured at considerably small separation. Due to this, and considering the high frequencies of operation, near field coupling effects such as crosstalk occur, which causes the degradation of the signals propagating by the lines. A methodology that allows us to obtain a microstrip line model to determine the RLGC parameters (resistance, inductance, conductance and capacitance) in common and differential modes depending on the frequency and the separation of the lines, neglecting the conversion of the modes is presented. From the results of these models, it is possible to calculate the S parameters for the coupled lines. The proposed models can be extrapolated to any desired separation, to analyze the effect of near-end and far-end crosstalk when the separation of the lines is increased. This work employs coupled microstrip lines with four different separations among them in order to propose a model. With the purpose of validating the results and verifying correlation, experimental dispersion parameters are compared with the parameters obtained from the model in the frequency domain (70 KHz to 10 GHz) and in the time domain (0 ns a 4 ns). |
