From: steve weir " EMI issues from microstrip are often greatly overstated. The big offenders on a PCB are: the cavity edges, and the components radiating above the PCB surface. Doug Smith has some good information on these types of subjects. Lee is passionate about his practical experience with M/S and no significant EMI issues." I was thinking more about the effect of making the surface trace wider (for lower loss) and further away from the ground plane. I assume that this increases EMI even though the impedence isn't changing. -tom ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
