Question
What PCB dielectric/laminate material should I be using with the ADA4530-1?
Answer
It is recommended to use the Rogers 4350B laminate with the ADA4530-1 in the highest performance applications. Rogers 4350B is a ceramic laminatethat is compatible with standard PCB production techniques and is widely available. It exhibits much better dielectric relaxation behavior incomparison to a standard FR-4 laminate. The ADA4530-1 evaluation board is a 4 layer PCB with a hybrid stackup. The top and bottom layers use Rogers4350B while the middle core layer is the conventional glass epoxy FR-4. This hybrid stackup is needed for mechanical strength purpose.
