AFE7444: PCB manufacture requirement

Part Number: AFE7444

Dear teams,

Please kindly take some suggestions about PCB manufacture requirement, there are few questions as below:

1. What value is Dk/Df of high-frequency PCB material?

2. Are there requirements or recommendations for PCB materials? i.e. Rogers RO4350B, Panasonic Meftron 6 or others?



  • Hi Ryan,

    For the AFE7444 we used a PCB material with a Dk of about 3.4 - 3.5. Usually for PCB materials you will look for a material that has very low loss and a low Dk. For recommendations on PCB material I would recommend Panasonic Megtron 6, Rogers RO4350B, and the newer Nelco Meterowave1000.
