Re: Altium (DMC) 26 GHz modules

Thanks Chris,

I've posted some pictures on the group pages of the TX mixer & PA and LO multiplier stage. I'll take some more if people are interested.

Hello Noel

There are certainly some very useful DMC synthesiser, filter, and
amplifier parts around. The devil is in the detail!

I brought a couple of 23GHz links eight or nine years ago, and there
were synthesisers which could easily be tweaked to use both as a
24.04880GHz narrowband beacon, and as a 23.606 ( Ithink ...) GHz LO.
Some of the cables were also worth salvaging: the Astrolab flexibles, in
particular, are rated for 24GHz use, and you don't find that sort of
thing every day ...

Modifying the units which I had wouldn't be easy without the right kit,
as they were made using ceramic substrates and lots of wire bonded chip

I wrote a brief note for 'Scatterpoint' at the time based on my
investigations of one synthesiser module. At the time there was other
information available on the net.
