Have you looked at Motorola's website?. There are a good number of
Application Notes there with amps from 10w to Kw's for HF to uWave
described in detail. There is also a company in US that stocks the
'hard to find' bits, and Kits, for them. Sadly I can't find the URL at
the moment.


Thanks!

Could be RF Parts?

No, The site I referred to sells Kits of all the hard to get parts for
the Motorola RF amps, at a very good price too. Far less than Mainline
used to sell the same thing.
I've had a search on the web tonight and can't find the damn place.

Communications Concepts continues to advertise in printed media.
They still have advertisements in RF Design, an electronics trade
publication.

Haven't looked at Communications Concepts web site lately but a
couple years ago their reproduced Motorola application notes,
most authored by Motorola's Helge Granberg, were of less than
best quality in PDF. Still readable, though.

Thanks PJ, I spent about 3 hours searching last night without success.
I wish we had a resource like that in UK.
Your help appreciated and the URL bookmarked and backed-up
