Re: Protective diodes across input connector

Hi Martin, 

I think the diodes are not really needed. Some people reported that they affect precision above 200 MHz, though I never observed this effect, probably caused by diodes quality. I don't use diodes in my devices any more, and none were damaged by static.

I have several schematics here, some with protective diodes across input
connector, some without them. What should be preferred? Should be the
diodes placed directly onto connector body or on the board?
