All of the work I do is proprietary, so normally it is not possible to show my work. However, I did the job below for a small startup company a number of years back that went out of business in the middle of the job, so I think it’s OK to show it now. I never got the chance to complete it.

This layout was originally done using PADS. I later imported it into Altium Designer and some features were garbled in translation.

This example illustrates the many different techniques used in PCB design:

CPW, microstrip, parallel lines, differential pairs, matched length, ground stitching, smoothed RF traces, thru center pad heat dissipation, RF shield mounting, and specialized footprints (Copper pours were removed for clarity).
