The standard 23cms amplifier from minikits should do what you want. The 18W 23 cms module will give you 3W output for DATV

It needs about 40mW for full output so you will need a driver amplifier. Somthing like the Gali 84 or 74.

That's too much gain for one box so keep them separate. Also you probably need some attenuation.
If all of that is too much for you - Bert Modderman does a built version and has options for lower power drive - around 0 dBm.

yes the mini kits driver board is probably all i need as i already have a bert amp..! its around 80mw drive for 18watts out fm so i would probably get around 10watts digital with a clean signal..
does anyone here have a driver amp they like to sell..?????
before i order a mini kits one..

I dont see anything i can use darko..
I need
0.032 mw -5dbm input and 80mw 29dbm outputs amplifier
Unless the -3db to 210mw maybe ok.. and i use the dtx1 at less rf drive to the amplifier.. i may have to attenuate the output of that
Inc shipping to wn68ns for this amplifier darko
