6 layer stackup

I'm no an expert, but it looks good, I would recomend the FR408 though. if you are having 3GHz, I'm assuming you will have up to 6Gbps, so a low loss tan material would be better. hope it helps.

Hi
This stackup looks good...
For upto 3 GHz signals, we can use FR4 materials.

6 layer pcb stackup

This stackup looks good. For high speed you can use FR408 or Rogers material.
