The present document includes the summaries of the projects carried out in the subjects of High Frequency Electronics Design, Methods of Simulation of Electronic Circuits and Modeling and Design of Circuits Based on Optimization, which make up the concentration area in high frequency electronic design. Those projects included the analysis of a parallel coupled band-pass filter for WLAN, the study of via stitching to improve signal integrity quality on high performance PCBs and the optimization of a single-stub shunt tuning network using space mapping techniques. The experience acquired when developing each of the practices has been directly applied to real work cases for the design of server boards in both aspects: electrically (schematics and components selection) and physically (PCB design).
