breadboarding picosecond stuff


I'm testing an MC10EP16VS part, a fast si-ge ecl buffer that has
programmable output swing. A simple copperclad breadboard works very
well, with fairly clean 200-or-so ps edges. The end-of-step drool is
fairly common on very fast stuff, which is why lots of people specify
20-80 percent risetimes, instead of the more common 10-90, for really
fast edges. It may get a little better on a real pc board.

The other circuit, lower-left, is a gaasfet thing that was interesting
but didn't work very well.
