I'm looking for some information about using some ettus SDR for sat work. I have a B210. What kind of amplifier can I use able to be driven with the 200 mW of the Tx/RX output, better if it's pass trought. My google search was unable to find some ham who has made somethin similar Is ther some similar work with another SDR? I would appreciate any kind of help... I'm a newbie... Thanks a lot. 73 Juan EB2FVT
Welcome to the club!
This is on the bleeding edge. Not all versions of code work.
The Mitsubishi RF amp chips can be biased to do FM or SSB. ( Non-linear or linear respectivley)
I'll take better video of the shack later. See youtube for my new efforts in this media.

Hi Juan,
You didn't mention specific frequencies, so I assume 2M and 70 cm.
Building appears to be the way to go, if you can. I'd probably use the Mitsubishi H2/H2S series of bricks. They come in various power levels up to about 60 watts with the drive requirements you're looking for.
See RF Parts www.rfparts.com and select the power module section.
For interfacing, check out Jim, W6PQL's boards.

Scroll down to the MosFet Module Amplifier kit.

Attached the B210 to the UHF antenna for FO-29. Didn't notice the uplink power was set on 50 watts until afterward. B210 could have cared less. Talked with Captain Yuri. Score one for National Instruments!
