Rick,
It sounds like you need a broadband equalizer circuit. ATC (American Technical
Ceramics)offers a line of Ultra Broadband Caps, Resistors and Inductors (up to
40 GHz). They have a new equalizer circuit designed for this very issue. I
couldn't find a link to the product on their website but you can contact them
directly for more details. It can be designed to be as small as 0103 and have
what ever insertion characteristics that you need. It can't be used in place of
a DC Block though.
Let me know if you need more information.
Everett
