Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all

I have an open and general question regarding
material such as Roger3000, LTCC or Ceramic..
I have heard people
complaning about those material at frequency above 30GHz, either for
the loss, for the unstable lateral dimensions or price.
has experience with those type of material for either packaging or circuit
and could give me more details.. What problems do people usually face
with those type of materials?
Is there a frequency at which there
is no solution for chip on package or it is to expensive(above $100/inch^2)??
or just to much twinking required???
I hope my question is not
to vague... and there is some kind of response...
