Really dumb thought - Bob Pease says that someone he knows (worked=20 with?) said to use 50.1 Ohms instead of just 50 Ohms - somehow, that=20 got rid of weirdness. Might it apply to your situation - I really don't know. But that=20 little tidbit of info got tucked into my brain when I read it and I'm=20 just passing it on. dwayne At 02:49 AM 6/7/2012, V G wrote: > This is what >LTSPICE is showing me for the calculated impedance graph (red) and I don't >really know why.
