--Help!-- I am working on a design for an active antenna
mounted external to jet aircraft. I am concerned about the
CTE mismatch between ceramic and plastic components
(including 2 16-pin SOICs)  and  FR-4 laminate. Can anyone
suggest materials/vendors for this type of application?

Thank you for any input,
