Abstract
As differential signaling becomes more and more desirable, innovative solutions must be sought to keep size and cost to a minimum. This thesis analyzes a combination differential-mode equalizer and common-mode filter (DME-CMF) realized on a two-layer microstrip board. Measurements up to 25 GHz are taken to explore the functionality of this device at and above the design frequency. The basics of S-parameters are reviewed, and the concept is expanded to include differential networks. Results in the form of differential S-parameters and eye diagrams are analyzed to judge the effectiveness of the DME-CMF, and future signal integrity applications are discussed.
