Ian:
Most of the filters I have built over the years have used the
linearizing diodes (I use CA3280's). Me personally, for multimode filters,
prefer this. I am afraid that this is about as far as the pro's and con's go
for me. In my latest projects, I have been sometimes laying out the board so
I can hook them up with or without linearizing diodes.
