@niconiconi Instead of going 4 layer I usually use a breakout board, which itself is a hassle for production... Seems you managed to do it all in 2 layers though, so thats good!
@niconiconi I would tend to agree with that. Hell I use ground planes on far less than that, and have been bitten in the ass when I didnt.
@freemo This is a 4 layer board with the standard S-P-G-S stackup. I personally don't trust anything above 1 GHz without dedicated ground planes.
