nope, sorry, but it was a more or less typical example of some of Kent
Britain's and others discoveries of easy ways to get onto microwave bands.
Raising the voltage on these chips does great things to the power output,
as that E^2/R goes up fast as E goes up a little ;-)

Another example was an amplifier with many microwave modules, most of the
power was used to produce a linear (digital compatible) output; junk that
overhead, and the power went up from 10 watts or so to over 100 watts ;-)

You might try emailing the North Texas Microwave Society or Kent directly?
http://www.ntms.org/ - we are having a major conference in October I
hope to attend, so I may have more notes there ;-) Kent is also the
author of the "cheap yagi" designs from VHF-CQ and other online sources.

sadly, there was a second seminar at Hamcom 2004 on resources for
microwave wanna-bees. The first were a series of older books on microwaves
and test equipment, with the sensible observation that most of the
affordable test gear being surplused now is described in use in these
older books ;-) The second was a series of newsletters and publications,
some in German/English, from RSGB, and ARRL on microwaves operations etc.

Some of these were described and seen to be quite pricey for the amount of
articles therein ;-( The NTMS has evidently made an effort to build up a
collection of articles and resources related to microwaves, rather than
have each member try to duplicate these costly and hard to find
references.

I am not seeing a lot in the way of homebrew microwave construction or
conversion articles, given some of the relatively easy projects I have
seen described at these seminars and in some ARRL materials I have etc.?
So the conference may turn up some more resources, I hope ;-)

Part of the motivation here is we are trying to "inherit" some big
roof-top microwave satellite dishes from our engineering school as these
get obsoleted as we go online with streaming video on demand. Our club's
roof access port is only ten feet from the bigger dish ;-) It will cost
the school major $ to take this stuff down, so it would save $ to let us
use it - and might provide lots of useful hands-on microwave experience
for some of our future graduates. That's my argument, anyway ;-)

If anybody knows of some microwave homebrew resource and project pages,
let me know!
