General question on Packaging and circuit Board - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hello everybody,

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.
Does anyone 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...

Thank you
JM

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
