Hello Zlatko,

In the UK complete 3400 MHZ IONICA 15 watt(20watt) amplifiers are sold for about 45 GBP. If you place a request at ukmicrowaves@yahoogroups.com maybe somebody has one left.
G3PHO describes here how he is using it in his transverter http://www.g3pho.free-online.co.uk/microwaves/9cm.html


Best regards

Halllo Frans!
Thanks for fast, nice and usefull advaice! I try to cach some IONICA on Friedrichshafen this year, but other was faster  Huilen. Toshiba PA was to expensiv for mee  Huilen
In meantime I recived gift from Lorenz/DL6NCI ( FLM3742-12 )  Lachen , and now I "must" make PA  Lachebek.
That is reason that I am looking for papers...
I find on internet some summary listing for Dubus. In Dubus Technick 2 page 200 is some article from DK1UV " 6W 3456MHz PA ". That is probably older from 1984. From this time I have some Dubus magazine, but there is NOT this article ! Is interesant that is article in Technick book and NOT in magazine  Verbaasd
I am not shure wich active elements is used there. That was before 1/4 century  Grijns Rollende ogen
Mybee somebody have documentation from old RF Module MT 3,4 Z 10 WA  ( ex DL2AM ) 9cm PA. Rollende ogen
Old DB6NT 9cm PA ( wich still sold Eisch ) is with 3 x MGF0905.. and not interested for me.
TNX & WBR !!!!
