“…Various parameter extraction methods such as the LCZ technique [1], the time domain reflection (TDR) method [2] and frequency domain methods [3]- [8] have been reported. Among them, the LCZ technique guarantees the performance of packages at only low frequencies and the TDR method assumes that transmission line parameters are frequency independent.…”

Ball grid array (BGA) packages have been characterized from one port S S S-parameter measurements by shorting and opening the connection on the ball side of BGA packages. Transmission line parameters (resistance, inductance and capacitance) using the 0 equivalent circuit model are extracted from the measured S S S11 parameter. Extracted resistances are strongly dependent on frequency, but extracted inductances and capacitances are nearly constant up to 500 MHz. Extracted capacitances are well matched to those measured from an LCR LCR LCR meter and calculated from a three-dimensional (3-D) simulator. Capacitance in a transmission line plays an important role in electrical performance for packages so that we may model a transmission line as a single capacitor. Extracted capacitances using the single capacitor model also well represent the measured S S S 11 . These results suggest that the single capacitor model can be efficiently used for the transmission line model in BGA packages up to 500 MHz. Index Terms-Ball grid array packages, capacitances, lumped element model, S S S-parameter measurements, transmission line parameters.

“…Some researchers have studied crosstalk in microstrip using even and odd mode analysis [1,7], others have analyzed the mutual inductances and capacitances [2,3,4,5,6]. Zhou [12] cited Leone [13] stating that certain approximations and assumptions were made that ignore the line width and field distribution, not because he was inadequate but because, "It is difficult to obtain solution with both simplicity and accuracy if one just studies the coupling in a direct way [12]."…”

DEDICATIONTo those who helped make this happen.iv ACKNOWLEDGMENTS I wish to express my gratitude toward my major professor, Dr. Grover Larkins, for his multifaceted support in helping me assemble this master's thesis. His encouragement played a key role in my ability to grow from the many challenges encountered in this experience.Many thanks to my wife, Marilen, for always believing in me and supporting me throughout this challenging stage of my life. Your patience toward the amount of time demanded of me to complete this work has been a silent sacrifice on your part that spoke volumes to me, I cannot appreciate that enough. The aim of this thesis is to identify coupling mechanisms for three line microstrip, stripline and microstrip with dielectric overlay structures as either inductive or capacitive, quantify through simulation and measurement the amount of crosstalk to be expected in terms of scattering parameters. A new method of crosstalk suppression is implemented into each three line structure by placing uniformly spaced short circuits down the length of the center transmission line.All structures were simulated over various physical and electrical parameters. Select microstrip structures, shielded and unshielded, were fabricated and measured to validate the effectiveness of the shielding technique. Shielding effectiveness was calculated from the measurements, and their results showed that the isolation between lines was increased by up to 20dB.

compensated. Without the use of optical amplification, the costs can be reduced further and still be possible to meet the requirement of EVM Ͻ12.5% up to 60 km and 2 mW of laser power. At last, a two-channel WDM system was tested and acceptable values of EVM were obtained even with an SOA working close to saturation, showing that normal SOAs can be used in these environments, decreasing the possible cost of amplification.

In this article, we will illustrate modeling of inhomogeneous quasi-TEM shielded broadside-coupled substrate striplines using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in strongly inhomogeneous media. We illustrate that FEM is suitable and effective as other methods for modeling shielded broadside-coupled substrate striplines. We specifically determine the capacitance per unit length, even mode impedance, odd mode impedance, and characteristic impedance of shielded broadside-coupled suspended striplines. Excellent agreement with some results obtained previously is demonstrated. We extended the modeling by designing our own model of shielded broadside-coupled inverted microstrip line and determine the capacitance per unit length, even mode impedance, odd mode impedance, and characteristic impedance.
