Hi Sean

I have done some work substituting Arlon 350(teflon with ceramic loading)
for FR4 and have
been able to double the bandwidth of previous generations. Going from FR4
to Getek will
not get you much, but if you go to Nelco 4000-13SI, you can expect a big
improvement in
the frequency dependent losses.

Good luck
Ron Miller
