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
the responses to the original posts.
Post subject: seeking millimeter wave collaborators for NASA research

There is an open NASA / NIAC BAA for game changing
technologies, and there is some interest in wireless
1) how can we increase
/ maximize DC to RF conversion efficiencies (35
- 350 GHz)?
2) what power efficiencies might
be possible in the short term, medium term and long
3) About what level of investment would
be required to improve device and chip conversion
efficiencies ? Over what time frame ?
what technical approaches might there be ?
5) for an example of out of the box thinking:
I hear that the losses in millimeter wave MMIC chips
are a combinationbof dielectric losses and skin
effect dissipation in conductors.
case of the latter, do you think there might be
potential tobreduce losses via employing superconductors
(instead of gold/silver) ?
Since about 1993,
the highest temperature superconductor is a ceramic
material consisting of thallium, mercury, copper,
barium, calcium and
with Tc = 138 K.
There could be funding via
NAIC BAA to pursue such research.
