Hi Tom, Thanks for this valuable info. I'm a little worried about opticap's solderibility. Do you have any experience with it? And another question, must I design microstrip lines to have same width as the cap width, or I can choose other line widths as long as they are of 50-ohm impedance? Regards. Hassan.
