Mitch -
I personally worked on one 4 layer design for an RF Transmitter that used a
sandwich of 2 RO4003 cores an a center layer of FR-4 prepreg. This design
preformed extremely well and was simple to tune. I have also bonded RO4350
with G-tek prepreg which formed a very rigid and thermal stable PWB.
Contact me off-line and I can recommend a fabricator for these types of
PWB's.

I have a "similar" question which hopefully someone can answer. I've
been asked by our engineering group if FR4 material, is compatible
with
the Rogers 3000 and 4000 materials? We'd like to make a board using
the
Rogers material for some circuitry and FR4 material with the other
circuitry.
Any luck?
